     View Summary

    The stretching properties of a [7]thiaheterohelicene framework, what we call molecular spring, have not been investigated so far, despite a variety of [7]thiaheterohelicene derivatives having very interesting characteristics due to both the rigidity arising from fused benzene rings and the flexibility like a spring originating from helical structure. In this study, a novel [7]thiaheterohelicene derivative, which has a disulfide moiety for bonding to a gold-coated substrate and a carboxy group for reacting with an amino-modified probe tip at each of its end groups, was synthesized in order to elucidate the elasticity of the [7]thiaheterohelicene framework by atomic force microscopy (AFM). The AFM force measurements were carried out using two carboxy-terminated disulfide derivatives with or without a [7]thiaheterohelicene moiety, and the deviation between two kinds of force-extension curves was related to the stretching originating from the [7]thiaheterohelicene framework here. Furthermore, its elasticity was compared to that of biphenyl, which is generally known as a rigid framework, using electrostatic state calculations.

  • Effect of photoirradiation on chromatographic separation of alkali metal ions using crowned-spirobenzopyran-immobilized silica

    Yoshio Nakahara, Yuki Yamaguchi, Hitoshi Iwamoto, Hidefumi Sakamato, Keiichi Kimura

    Analytical Methods   4 ( 12 ) 4025 - 4029   2012.12

     View Summary

    We successfully developed a novel photocontrollable chromatographic system for separation of alkali metal ions. Based on the finding that the metal-ion complexation of spirobenzopyran derivatives bearing a crown ether moiety, which we call crowned spirobenzopyran, can be drastically changed by photoirradiation, crowned spirobenzopyrans were immobilized covalently onto silica gels for stationary phases of ion chromatography. Under dark or UV-light irradiation conditions, a marked separation between Li+ and K+ was attained by silica gels modified chemically with crowned spirobenzopyran bearing an 18-crown-6 ring. On the other hand, no significant separation between the two metal ions was found under visible-light irradiation conditions. This result originates from the fact that the K+-complexing ability of crowned-spirobenzopyran-immobilized silica is switched by photoisomerization of the spirobenzopyran moiety from its merocyanine form to spiropyran form. Furthermore, computer simulations of separation of alkali metal ions by crowned spirobenzopyrans in the silica phase were conducted using molecular dynamics calculations. © 2012 The Royal Society of Chemistry.

     View Summary

    We fabricated pentacene field-effect transistors using polysilsesquioxane (PSQ) as a gate dielectric material that can be cured at sufficiently low temperatures for low cost plastic substrates. The surface roughness of the PSQ films were reduced by the introduction of 3-methacryloxypropyl groups, and their surface energy was controlled to match with that of the pentacene layers by the introduction of phenyl groups. Consequently, the carrier mobility was improved by two orders of magnitude and reached 0.38 cm(2) V-1 s(-1). (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4742891]

     View Summary

    A novel co-polymer, P-PBTx, is a promising emitting material for white OLED. Appearance of unexpected yellow emission in EL is a key point, but its origin has not been clarified yet. Photo-luminescence properties of the copolymer were investigated in comparison with those of its monomer as well as two component molecules. An PL yellow band was also observed even in a film of a chromophore molecule at low temperature, depending on the position of an inhomogeneous film. Then, modified molecule center such as a dimer or an excimer of neighboring chromophores is a possible origin of the PL yellow emission.

     View Summary

    Copolymers bearing azacrown ether and anthracene moieties were synthesized using methacrylates of N-2-ethyl-azacrown ether or 9-hydroxymethylanthracene. Their fluorescence behaviors in the presence of alkali metal ions were measured in THF:H2O = 10:1 solution. Maximum fluorescence intensities for copolymers bearing aza-12-crown-4, 15-crown-5 and 18-crown-6 were observed for with Na+, K+ and K+, respectively. The largest change in fluorescence behavior was observed for the copolymer bearing aza-18-crown-6 in the presence of K+. The magnitude of the increase in the fluorescence intensity was related to the content of the crown ether moiety. The time-dependent changes in the fluorescence spectra using photo-irradiation were also investigated. (c) 2011 Elsevier Ltd. All rights reserved.

     View Summary

    The photo-luminescence (PL) and electro-luminescence (EL) of a novel organic material, benzodithiophene/triphenylamine copolymer (P-PBTx, n=5-6) were investigated. The PL exhibited wide blue emission at room temperature, which is attributed to fluorescence from a chromophore, benzodithiophene moiety, from results of spectral analysis and decay profile. The EL, however, exhibited white emission consisting of wide blue (B) and yellow (Y) bands, although it was prepared with P-PBTx as a single emitting material. The Y-band was slightly observed at 7 K and found to possess long lived component of 19 ms lifetime. The origin of the Y-band efficiently stimulated by carrier injection is supposed to be a charge-transfer state between benzodithiophene and triphenylamine moieties. The long lived component could be explained by lowered transition probability caused by charge separation. (c) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

    Two novel fluoroionophores, N-(7-hydroxy-4-methylcoumarin-8-ylmethyl)-3,9-dithia-6-azaundecane (1) and N-(7-hydroxy-4-methylcoumarin-8-ylmethyl)-3,9-dithia-6-azaundecane (2), were synthesized as fluorescence extractants for selective silver determination. The absorption and fluorescence spectra were measured in aqueous 1,4-dioxane solution (28 v/v%) in the absence and presence of silver ion, and their acid dissociation constants were determined from the pH-dependent spectral changes. In the liquid-liquid extraction of some metal ions from neutral aqueous solution into dichloromethane phase, compounds 1 and 2 exhibited excellent silver ion selectivity, and dramatic fluorescence spectral changes were observed in the dichloromethane solutions containing these compounds. The determination limit of 2 for silver ion was 2.0 x 10(-8) mol dm(-3) in the liquid-liquid extraction.

     View Summary

    Metal ion complexes of crown ether derivatives bearing two spirobenzopyran moieties were synthesized and their structural features were studied by X-ray crystallography and NMR spectroscopy. The resulting X-ray crystal structure for the Ca2+ complex of diaza-12-crown-4-bis(spirobenzopyran) showed that both of two spirobenzopyram moieties were isomerized from their spiropyran forms to the corresponding merocyanine forms and their phenolate anions interacted with Ca2+ bound to its crown ether moiety. The crystal structure also revealed its syn conformation whose two spirobenzopyran moieties oriented on the same side of the crown ether moiety. Furthermore, density functional theories (DFT) calculations were carried out in order to predict energetically stable conformation of diaza-18-crown-6-bis(spirobenzopyran). (C) 2008 Elsevier B.V.

    BULLETIN OF THE CHEMICAL SOCIETY OF JAPAN ( CHEMICAL SOC JAPAN )  81 ( 10 ) 1322 - 1330   2008.10  [Refereed]

     View Summary

    Benzo[1,2-b:4,3-b']dithiophene/triphenylamine copolymers P-2eh (with no rnethyl substituents) and P-Me and P-2Me (with methyl substituents at triphenylamine sites) were synthesized by Stille coupling reactions. In the ground state, the methyl substituents at the ortho positions to the BDT unit oil the triphenylamine (TPA) moiety in P-Me and P-2Me caused twisting of the polymer structure and clearly limited conjugation of the polymer backbones. However, in their excited states, all of these copolymers were shown to have planar structures, and almost the same emission maxima were observed. This result indicates that, in the excited states, pi-conjugation of the polymer backbone results in the adoption of a more stable planar structure rather than the twisted structure observed in the ground state. The maximum EL efficiencies of devices based on P-Me and P-2Me were about three times higher than that of P-2ch due to restricted pi-stacking/aggregation of the Conjugated copolymers in the solid state and improvements in thermal and electrochemical stability.

  • Electrospray-ionization mass spectrometric determination of surfactants based on inclusion with α-cyclodextrin

    Nobuyuki Negoro, Haruhisa Konishi, Hidefumi Sakamoto, Keiichi Kimura

    Journal of Inclusion Phenomena and Macrocyclic Chemistry   62 ( 1-2 ) 59 - 63   2008.10  [Refereed]

     View Summary

    Cyclodextrin (CD) is well known to include the lipophilic compounds to form inclusion complexes, because it has a hydrophobic cavity and a hydrophilic outside surface. The CD complexation is useful for determination of particular surfactants by mass spectrometry due to the increase in the weight of surfactant. In this study, the anionic surfactant was determined directly as its CD-complex in methanol/water (1:1) solution by electrospray-ionization mass spectrometry (ESI-MS), while the nonionic and cationic surfactants were determined indirectly from the concentrations of a deprotonated CD ion, which was derived from the uncomplexed CD.

  • Molecular design of tetraazamacrocyclic derivatives bearing a spirobenzopyran and three carboxymethyl moieties and their metal-ion complexing behavior

    Koji Machitani, Hidefumi Sakamoto, Yoshio Nakahara, Keiichi Kimura

    Analytical Sciences   24 ( 4 ) 463 - 469   2008.04  [Refereed]

     View Summary

    Tetraazacyclododecane and tetraazacyclotetradecane derivatives bearing a spirobenzopyran and three carboxymethyl moieties, 1 and 2, and a diethylenetriamine derivative bearing a spirobenzopyran and four carboxymethyl moieties 3 were synthesized. The isomerization behaviors based on the spirobenzopyran moiety of these ligands were studied by UV-visible spectrophotometry in aqueous solutions containing various metal ions at neutral pH. These ligands formed stable 1:1 complexes with lanthanide ions, while the spirobenzopyran moiety was isomerized to its corresponding merocyanine form even under dark conditions. In aqueous solutions containing a lanthanide ion, the absorption spectra of 1 or 2 showed remarkable blue shifts, while absorbances at the maximum absorption wavelengths in the visible region were enhanced
    such changes are attributable to the isomerization to the merocyanine form of the spirobenzopyran moiety. These results suggest that the phenolate anion of the merocyanine moiety interacts very strongly with a lanthanide ion bound by the complexing moiety because of the high charge density of lanthanide ions. In contrast, the absorbance of merocyanine form was decreased by the complexation of the macrocyclic ligand with transition metal ions, such as Cu2+ and Zn2+. This result indicates that macrocyclic ligands, 1 and 2, formed complexes with transition metal ions only by the aminocarboxylate moieties, and the phenolate ion of merocyanine moiety was not able to participate in the complexation. This conclusion was also demonstrated by density functional theory calculations. 2008 © The Japan Society for Analytical Chemistry.

  • Absorption- and fluorescence-spectral sensing of alkali metalions in anionic micelle solutions containing crowned spirobenzypyrans

    H. Sakamoto, T. Yamamura, K. Takumi, K. Kimura

    JOURNAL OF PHYSICAL ORGANIC CHEMISTRY ( JOHN WILEY & SONS LTD )  20 ( 11 ) 900 - 907   2007.11  [Refereed]

     View Summary

    Spirobenzopyran derivatives bearing a monoazacrown ether moiety (monoaza-12-crown-4, -15-crown-5, and -18-crown-6) and an octadecyl group as a lipophilic moiety, called crowned spirobenzopyrans were synthesized, which can be dissolved in anionic micelle solutions. We examined absorption-and fluorescence-spectral changes of micelle solutions containing a crowned spirobenzopyran on addition of alkali metal ions. The crowned spirobenzopyrans are in their merocyanine form in an anionic micelle solution even under dark conditions, showing a significant absorption in the visible region which is attributable to the merocyanine moiety. Crowned spirobenzopyran bearing a monoaza-12-crown-4 moiety exhibited a drastic hypsochromic shift in the absorption and also an enhanced fluorescence on addition of Li+ to the micelle solutions under alkaline conditions. These spectral changes can be attributed to a strong interaction between Li+ bound by the crown ether moiety and a phenolate ion of the merocyanine moiety. Similar absorption and fluorescence-spectral changes were induced in the anionic micelle solutions containing the other crowned spirobenzopyrans on addition of alkali metal ions. The intensity of the absorption-spectral changes in the systems of the three crowned spirobenzopyrans, however, differed from each other, depending on the strength of interaction between a metal ion bound to the crown ether moiety and the phenolate ion of the merocyanine moiety. On the other hand, the extent of enhanced relative fluorescence intensity is dependent on the strength of interaction between metal ion and a nitrogen atom of azacrown ether moiety, because the fluorescence spectrum is quenched by photoinduced electron transfer (PET) from the nitrogen atom to the merocyanine moiety.

    In order to apply micelles to novel type of separation and analytical chemistry, a crowned spirobenzopyran derivative, which is a spirobenzopyran derivative bearing a crown ether moiety as the hydrophilic part and a long alkyl chain as the lipophilic moiety, was solubilized in aqueous micelle solutions consisting of an anionic surfactant. Structural changes of the micelle based on the photochromic isomerization of crowned spirobenzopyran were studied by fluorescence spectra and a light scattering method. It was found that the critical micelle concentration (cmc) was changed appreciably by photoirradiation, while the particle size and the aggregation number of surfactant were slightly changed.

    JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY ( AMER SCIENTIFIC PUBLISHERS )  6 ( 6 ) 1741 - 1749   2006.06  [Refereed]

     View Summary

    A vinyl copolymer carrying crown ether and spirobenzopyran side chains, which undergoes significant photoinduced rheology changes, i.e., contraction and extension of its polymer chain, was applied to a material for photocontrol system of solvent permeation rate, so-called, photochemical valve. Macroporous polyethylene membranes coated by the crown ether-spirobenzopyran copolymer can work as a functional membrane controlling solvent permeation rate photochemically. UV-light irradiation on the photoresponsive membrane decreased the permeation rate of hexane, due to the increased polarity of the membrane pore, which was in turn derived from the photoisomerization of its spirobenzopyran moiety to the corresponding ionic merocyanine form. The following visible-light irradiation on the membrane restored the permeation rate by isomerization back to the electrically neutral spiropyran form. To the contrary, the permeation of ethanol through the membrane was enhanced by UV-light irradiation due to the increase in the apparent membrane pore size induced by the polymer chain contraction and vice versa by visible light. Similar photoresponses in the permeation rate of nonpolar and polar solvents were also observed with a sintered glass filter modified chemically by both silane-coupling reagents containing crown ether and spirobenzopyran moieties.

    JOURNAL OF SYNTHETIC ORGANIC CHEMISTRY JAPAN ( SOC SYNTHETIC ORGANIC CHEM JPN )  64 ( 1 ) 61 - 74   2006.01  [Refereed]

     View Summary

    Organic compounds; whose structure and absorption spectrum are changed by photoirradiation with a particular wavelength and vise versa by the other light irradiation, are called photochromic. The metal-ion complexing abilities and selectivities of several crown ether derivatives bearing photochromic moiety have been so far investigated under photoirradiation conditions, and remarkable changes in their properties were often realized. Several compounds, such as crowned photochromic compounds, are isomerized and their absorption spectra are simultaneously changed by metal ion complexation even under dark conditions. In this paper, quantitative evaluation of metal-ion complexing abilities of crowned photochromic compounds caused by photoirradiation with electrospray ionization mass spectrometry (ESI-MS) was described. Liquid-liquid extraction and liquid membrane transport using photochromic crown compounds with photoirradiation were also shown as metal-ion separation methods. Absorption spectral changes with metal ion complexation of photochromic crown compounds were applied to metal ion determination using liquid-liquid extraction and micelles containing them.

     View Summary

    Several azacrown ether derivatives, which are monoaza-2-crown-4, -15-crown-5, and -18-crown-6 and diaza-12-crown-4 and -18-crown-6, beating one or two spirobenzopyran(s), which we call crowned spirobenzopyran or crowned bis(spirobenzopyran), were synthesized and were used as carriers for liquid membrane transport of alkali metal ions. The passive alkali metal transports through liquid membranes containing crowned spirobenzopyrans were carried out under dark, and UV- and visible-light irradiation conditions. The metal ion transport was accelerated and retarded by UV- and visible-fight irradiation, respectively. On the other hand, the photoresponse of the metal ion selectivity in membrane transport by crowned spirobenzopyrans was different, depending on the kind of crown ether units. Especially, diaza-12-crown-4-bis-(spirobenzopyran) exhibited an excellently selective and effective transporting ability for Li+. The uphill transports of Li+ through a liquid membrane containing monoaza-12-crown-4-spirobenzopyran or diaza-12-crown-4-bis(spirobenzopyran) were realized under the conditions where the same aqueous solution was used as the source and receiving phases with UV- and visible lights being irradiated onto the boundary phases between the source and membrane phases and between the receiving and membrane phases, respectively. The uphill transport of U. from the source to receiving phases through a liquid membrane containing a crowned spirobenzopyran was also attained by the proton-concentration gradient between the source and receiving phases under dark conditions, and the transporting ability was remarkably increased by photoirradiation.

    The photoinduced changes of metal-ion extractability of crown ether derivatives bearing three or four spirobenzopyran moieties and their analogues were studied using 1,2-dichloroethane as the organic solvent. Under dark conditions, these compounds extracted Cu2+, Ag+, and Pb2+ with their counteranions from the aqueous phase to the organic phase. The extraction equilibrium constants of the photochromic crown ether derivatives for Cu2+ and Ag+ were determined successfully. Under UV-light irradiation conditions, the extraction of Cu2- by crowned tris(spirobenzopyran) was enhanced, while that of Ag+ was suppressed. During the competitive metal-ion extraction of crowned oligo(spirobenzopyran)s between Cu2+ and Ag+, the metal-ion selectivity was reversed explicitly by photoirradiation. © The Japan Society for Analytical Chemistry.

    MACROMOLECULES ( AMER CHEMICAL SOC )  37 ( 5 ) 1871 - 1876   2004.03  [Refereed]

     View Summary

    Vinyl polymers incorporating a crowned spirobenzopyran moiety at the side chain were synthesized, and their alkali metal-ion complexation, photochromism, and photoresponsive ion-conducting behaviors were studied in comparison with similar polymers incorporating crown ether and spirobenzopyran moieties independently. The metal-ion complexation by their crown ether moiety significantly affected the photochromism of their spirobenzopyran moiety. The crowned spirobenzopyran polymers are similar to their corresponding monomeric analogue in their metal-ion complexing property and photochromism, with some difference induced by polymer effect. Almost no significant aggregation of the photoinduced merocyanine moiety was found in the crowned spirobenzopyran polymer, unlike the polymers carrying spirobenzopyran and crown ether moiety independently. The crowned spirobenzopyran polymers were applied successfully as components of photoresponsive ion-conducting materials.

    JOURNAL OF THE AMERICAN SOCIETY FOR MASS SPECTROMETRY ( ELSEVIER SCIENCE INC )  14 ( 10 ) 1110 - 1115   2003.10

     View Summary

    The photoinduced changes of metal-ion complexing ability of crowned spirobenzopyran derivatives were studied by using electrospray ionization mass spectrometry (ESI-MS). Stability constants for the complexation with various metal ions in methanol under visible-irradiation conditions were determined for the first time by ESI-MS. It was found that the stability constants of crowned bis(spirobenzopyran) derivatives with metal ions are decreased dramatically by visible irradiation due to the disappearance of powerful ionic interaction between phenolate anion(s) of the merocyanine form of their spirobenzopyran moiety and a metal ion bound to their crown ether moiety, and the decrease in the stability constants is more pronounced for the multivalent metal-ion complexes.

  • Application of photoionizable crowned spirobenzopyrans to flow-injection extraction-spectrophotometry for lithium ion

    Makoto Nakamura, Takeshi Fujioka, Hidefumi Sakamoto, Keiichi Kimura

    Bunseki Kagaku   52 ( 6 ) 419 - 424   2003.06

     View Summary

    A system for the flow-injection analysis of Li+ was designed for the first time, using (nomoaza-12-crown-4)-spirobenzopyran and (diaza-12-crown-4)-bis(spirobenzopyran) as extraction-spectrophotometric reagents. The photoirradiation effect on Li+ extraction was studied. In this flow-injection system with (diaza-12-crown-4)-bis(spirobenzopyran), which has a high stability constant for Li+, the extractability of Li+ was increased under UV irradiation (300-400 nm) conditions compared with under dark conditions, while being decreased under visible-light irradiation (&gt
    500 nm) conditions. This behavior was proved quantitatively by using flame spectrophotometry and conductometry. For Li+ flow-injection analysis with (diaza-12-crown-4)-bis(spirobenzopyran), UV irradiation, therefore, amplified the sensitivity owing to an increase in the Li+ extractability.

  • Molecular design and applications of photochromic crown compounds - How can we manipulate metal ions photochemically?

    K Kimura, H Sakamoto, M Nakamura

    BULLETIN OF THE CHEMICAL SOCIETY OF JAPAN ( CHEMICAL SOC JAPAN )  76 ( 2 ) 225 - 245   2003.02

     View Summary

    The design and applications of photochromic crown compounds are reviewed here. Such compounds exhibit the possibility of distinct photochemical control of metal-ion complexation, based on the ionic interactions of their photoionized photochromic moieties. Crowned spirobenzopyran derivatives which the authors designed, when isomerized to their corresponding merocyanine form by UV irradiation, can afford an additional binding site for a metal ion complexed by their crown ether moiety in a sophisticated way, i.e., by the six-membered chelate formation with the phenolate oxygen atom and the crown-ether-ring nitrogen atom. The crowned spirobenzopyrans, therefore, have their metal-ion complexing properties modified remarkably by photoirradiation, like the crowned spironaphthoxazines that are more photolabile than the spirobenzopyran derivatives. Crowned spirobenzothiopyrans possess an affinity to softer metal ions such as silver ion, which promotes their photoisomerization to the open form. Crowned bis(spirobenzopyran)s are highly selective for multivalent metal ions in the photochemical control of metal-ion complexation. Photochromic crown compounds such as crowned triphenylmethane dyes, when undergoing intermolecular photoionization, exhibit clear-cut photocontrol systems of metal-ion complexation, which are very attractive for applications, especially in materials chemistry. Polymerization of crowned spirobenzopyran and Malachite Green may make it easier to apply the photochromic crown compounds practically. Remarkable polymer effects also appear in the photochromic crown ether polymers; these include photoinduced switching between precipitation and solubilization in vinyl copolymers of spirobenzopyran and crown ether monomers. Several examples are described of the applications of photochromic crown compounds in materials and analytical chemistry, i.e., photo-responsive ionic conduction and photoenhanced ion sensing and separation.

  • Cation complexation, photochromism, and aggregation of copolymers carrying crown ether and spirobenzopyran moieties at the side chains

    K Kimura, M Nakamura, H Sakamoto, RM Uda, M Sumida, M Yokoyama

    BULLETIN OF THE CHEMICAL SOCIETY OF JAPAN ( CHEMICAL SOC JAPAN )  76 ( 1 ) 209 - 215   2003.01

     View Summary

    Methacrylate monomers containing monoaza-12-crown-4 and spirobenzopyran moieties were copolymerized to obtain polymers carrying their moieties at the side chains. The crown ether-spiropyran polymers can bind alkali metal ions with their crown ether moiety in the selectivity order of Na+ > K+ > Li+. The spirobenzopyran moiety, on the other hand, undergoes UV-light-induced isomerization from its spiropyran to the merocyanine form, leading to merocyanine aggregate formation. The metal-ion complexation of the crown ether moiety enhanced interpolymer merocyanine aggregation by extending the polymer chain on the basis of the electrostatic repulsion between the complexed metal ions. Thus, tetrahydrofuran solutions of a crown ether-spiropyran copolymer with 1:1 composition of the moieties led to significant polymer precipitation on UV irradiation in the presence of an alkali metal ion, especially Li+. The photo-chromism and aggregate formation were studied in detail by absorption and fluorescence spectrometry and by light scattering measurements.

    Novel ion-exchange resins bearing various kinds of polythiazaalkane moiety were prepared by using polystyrene and TOYOPEARL. which is composed of poly(vinyl alcohol), as matrixes. The adsorption of silver ion from aqueous solution was completed within 1 h by TOYOPEARL based resins, while that by polystyrene based resins was not accomplished for 24 h. All resins bearing polythiazaalkane moiety exhibited the selective adsorption for silver ion, and the efficiency of silver ion absorption was primarily governed by the number of sulfur atoms and the structures of polythiazaalkane moieties. The adsorption and the elution behavior of the TOYOPEARL based resin packed into columns for silver ion were examined in the flow system, and the highly selective enrichment of silver ion was observed using the resin with monothiazaalkane.

  • Liquid-liquid extraction of alkali metal ions with photochromic crowned spirobenzopyrans

    H Sakamoto, T Yokohata, T Yamamura, K Kimura

    ANALYTICAL CHEMISTRY ( AMER CHEMICAL SOC )  74 ( 11 ) 2522 - 2528   2002.06

     View Summary

    On the liquid-liquid extraction using 1,2-dichloroethane as an organic solvent, the crowned spirobenzopyrans exhibited textractability in the following order: Li+ much greater than Na+ > K+ greater than or equal to tetramethylammonium ion (TMA(+)), Li+ > Na+ much greater than K+ > TMA, and Na+ > K+ much greater than Li+ > TMA(+) for spirobenzopyran derivatives bearing monoaza-12-crown-4, 1; monoaza-15-crown-5, 2; and monoaza-18-crown-6, 3; respectively, under dark conditions. The ion selectivity of 1 depends on the metal-ion complexing ability of monoaza-12-crown-4. Even 2, which carries a 15-crown-5 moiety, showed Li+ selectivity because of the much stronger interaction of Li+ with the phenolate ion of the merocyanine form of 2 than that of Na+. The Na+ selectivity of 3 is also attributed to the ionic interaction with the phenolate ion of the merocyanine form, since the ionic interaction prefers Na+ to K+ regardless of the higher affinity of the 18-crown-6 ring itself to the latter ion. The Li+ extraction into the organic phase with 1 was enhanced by UV irradiation (300-400 nm), while some depression in the extraction was found by visible irradiation (>500 nm). The effect of visible irradiation on the Li+ complexing ability of I was also examined with electrospray ionization mass spectrometry.

  • Synthesis and photochromism of spirobenzopyrans and spirobenzothiapyran derivatives bearing monoazathiacrown ethers and noncyclic analogues in the presence of metal ions

    JOURNAL OF ORGANIC CHEMISTRY ( AMER CHEMICAL SOC )  67 ( 7 ) 2223 - 2227   2002.04

     View Summary

    Spirobenzopyrans bearing monoazathiacrown ethers and noncyclic analogues were synthesized, and their ion-responsive photochromism depending on the dual metal ion interaction with the crown ether and the phenolate anion moieties was examined using alkali and alkaline-earth metal ions, Ag+, Tl+, Pb2+, Hg2+, and Zn2+. The prepared spirobenzopyrans showed a selective binding ability to Mg2+ and Ag+ with negative and positive photochromism, respectively. Among the metal ions, only Ag+ facilitated photoisomerization to the corresponding merocyanine form. Depending on the ring size of the monoazathiacrown ether moieties, soft metal ions such as Hg2+ and Ag+ showed significant shifts in the UV-vis absorption spectra, while hard metal ions such as Mg2+, Zn2+, and Pb2+ did not afford any meaningful shift. This result reflects that the monoazathiacrown ether and phenolate anion moieties prefer soft and hard metal ions, respectively. Therefore, the Mg2+ and Ag+ selectivities are mainly derived from the phenolate anion and monoazathiacrown ether moieties, respectively. On the other hand, a spirobenzothiapyran bearing 3,9-dithia-6-monoazaundecane showed a remarkable selectivity to Ag+.

  • High stability constants for multivalent metal ion complexes of crown ether derivatives incorporating two spirobenzopyran moieties

    M Nakamura, T Fujioka, H Sakamoto, K Kimura

    NEW JOURNAL OF CHEMISTRY ( ROYAL SOC CHEMISTRY )  26 ( 5 ) 554 - 559   2002

     View Summary

    The metal ion complexing behavior of diazacrown ether derivatives possessing two spirobenzopyran moieties has been studied under dark conditions. Introduction of two spirobenzopyran moieties into diazacrown ethers resulted in interesting metal ion complexation abilities, along with isomerization of the spirobenzopyran moieties to the corresponding merocyanine form. The extremely high affinity for multivalent metal ions observed is due to an ionic interaction between the two phenolate anions and the multivalent metal ion. This finding is supported by absorption spectral measurements and electrospray ionization mass spectrometry. Stability constants for complex formation with various metal ions in methanol under dark conditions have been determined for the first time using mass spectrometry. It was found that the stability constants for crowned bis(spirobenzopyran) complexes with high charge density metal ions are much greater than those for the parent crown ether rings. Specifically, the La3+ complex of the diaza-18-crown-6 derivative carrying two spirobenzopyran moieties possesses an extraordinarily high stability constant of greater than 10(11) M-1 in methanol.

     View Summary

    Metal-ion complexation of crown ether derivatives incorporating one and two spirobenzopyran units was investigated by electrospray ionization mass spectrometry. The crowned spirobenzopyran derivatives exhibited very different metal ion-complexing behavior from their corresponding parent crown ether rings, preferring multivalent to monovalent metal ions owing to the additional ionic interaction with the nitrophenolate anion of the merocyanine moiety. The on-line photochemical reaction for mass spectrometry indicated that the metal ion-complexing ability and ion selectivities of the crowned spirobenzopyrans can be switched photochemically, taking advantage of the difference between the spiropyran and merocyanine isomers.

    JOURNAL OF THE CHEMICAL SOCIETY-PERKIN TRANSACTIONS 2 ( ROYAL SOC CHEMISTRY )  ( 11 ) 2539 - 2544   1999.11

     View Summary

    Potential response and its photoresponse for plasticized-poly(vinyl chloride) membranes containing a lipophilic crowned spirobenzopyran were surveyed and compared with those for membrane systems of a spirobenzopyran derivative not carrying any crown ether moiety. On UV-light irradiation, an intriguing type of time-course change was found with the membrane potential for the crowned spirobenzopyran system in the presence of alkali metal ions, ie., the potential first increases and then decreases. The photoresponse profile for the crowned spirobenzopyran system was affected considerably by the sort of metal ions and the pH conditions of aqueous phases. This phenomenon is explained by an ion-exchange mechanism specific to crowned spirobenzopyran, that is, fast proton exchange followed by slow metal-ion exchange of its merocyanine form. The system for the corresponding spirobenzopyran without crown ether moiety exhibited a steady potential photoresponse that depends on the pH conditions of aqueous phases.

  • Synthesis and silver ion complexation behavior of fluoroionophores containing a benzothiazolyl group linked to an N-phenylpoly-thiazaalkane moiety

    JOURNAL OF THE CHEMICAL SOCIETY-PERKIN TRANSACTIONS 2 ( ROYAL SOC CHEMISTRY )  ( 6 ) 1273 - 1279   1999.06  [Refereed]

     View Summary

    Cyclic and acyclic polythiazaalkane derivatives bearing a benzothiazolyl group as a fluorophore have been synthesized. The protonation and the metal ion complexation behavior were studied in a 1,4-dioxane-water (52/48 v/v) solution by spectrophotometry and/or spectrofluorometry. The changes in the absorption spectra (blue shift and hypochromic effect) and the fluorescence emission spectra (quenching) were observed by the addition of Ag+ ion selectively. On complexation with the Ag+ ion, the degree of the spectral changes of the benzothiazole derivatives is dependent on the extent of the interactions of the complexed Ag+ ion with the nitrogen atom of the polythiazaalkane moiety and with the benzothiazolylphenyl moiety. The complexation and the protonation behavior of the benzothiazole derivatives were investigated using H-1 NMR spectroscopy.

  • Silver ion selective fluoroionophores based on anthracene-linked polythiazaalkane or polythiaalkane derivatives

    J Ishikawa, H Sakamoto, S Nakao, H Wada

    JOURNAL OF ORGANIC CHEMISTRY ( AMER CHEMICAL SOC )  64 ( 6 ) 1913 - 1921   1999.03

     View Summary

    A dozen novel fluoroionophores have been synthesized which are polythiazaalkane and polythiaalkane derivatives coupled with an anthracene moiety by methyl, carbonyl, or methylphenylene bridging groups. The protonation and metal ion complexation behavior of analogues were examined in 1,4-dioxane--water solutions spectrophotometrically and spectrophotofluorometrically. The fluoroionophores, 1, 2, 5, and 6 contain basic nitrogen atoms and quench the fluorescence in the free forms because of photoinduced electron transfer (PET) from a nitrogen atom to a photoexcited anthracene unit. The fluorescence was recovered by the protonation on the nitrogen atom. The fluorescence intensities of the other fluoroionophores used here were not dependent on the pH of the solution. On the complexation of the protonated fluoroionophores 1, 2, 5, and 6 with metal ions under the acidic condition, the fluorescence intensities were decreased by the addition of silver ion selectively. Under the same conditions, the other fluoroionophores exhibited a decrease of the fluorescence intensity with the addition of silver ion selectively. These results imply that the fluoroionophores could form complexes and release a proton from the nitrogen atom of the protonated fluoroionophores. The quenching of the fluorescence of the complexed fluoroionophores 3, 4, 7, and 8-12 could be caused by the interaction of a silver ion with a ct-electron of the anthracene unit. The degree of spectral change on the complexation with silver ion is primarily dependent on the strength of the interaction of the bound silver ion with nitrogen atom, far 1, 2, 5, and 6, or with a pi-electron of the anthracene unit, for 3, 4, 7, and 8-12.

    Cation complexation and subsequent isomerization of a diaza-18-crown-6 derivative possessing two spirobenzopyran units, crowned bis(spirobenzopyran), were investigated in solution and compared with those of its corresponding derivative incorporating only one spirobenzopyran unit. Complexation of multivalent metal ions, especially Ca2+ and La3+, by crowned bis(spirobenzopyran) enhanced the isomerization of the spirobenzopyran moiety to the corresponding merocyanine form due to the effective intramolecular interaction between a crown-complexed cation and two phenolate anions in the cation complexes of the merocyanine form. Significant photoinduced switching of ionic conductivity was realized in composite films containing crowned bis(spirobenzopyran) and a calcium salt.

    A series of N-phenylpolythiazaalkane derivatives: the cyclic derivatives 4-phenyl-1-thia-4-azacycloexane 1, 7-phenyl-1, 4-dithia-7-azacyclononane 2, 10-phenyl-1, 4, 7-trithia-10-azacyclododecane 3 and 13-phenyl-1, 4, 7, 10-tetrathia-13-azacyclopentadecane 4 and acyclic derivatives 6-phenyl-3,9-dithia-6-azaundacane 5 and 9-phenyl-3.6.12,15-tetrathia-9-azaheptadecane 6, have been studied towards complexation with Ag+ ion. Single crystals of two Ag(I) complexes, [Ag(2)(2)][CF3SO3] and [Ag(4)][CF3SO3] were prepared and their structures were determined in the crystalline state by X-ray diffraction. In [Ag(2)(2)][CF3SO3], two bidentate 2 ligands, in which two sulfur atoms act as coordination sites, sandwich Ag(I) to give a four-coordinate complex in near tetrahedral geometry. In [Ag(4)], Ag(I) enters into a cavity composed of four sulfur atoms to give a distorted tetrahedral geometry. In [Ag(4)], Ag(I) enters into a cavity composed of four sulfur atoms to give a distorted tetrahedral geometry. The changes of the chemical shifts in H-1 NMR spectroscopy by the addition of CF3SO3Ag indicate that 1 and 2 exhibit small downfield shifts only for the protons of the thioether moiety, while 3, 4, 5 and 6 show drastic shifts for all protons. Ag+ ion complexation with N-phenylpolythiazaalkane and polythiaalkane derivatives, which were used for comparison, was studied in acetonitrile solution by potentiometry. Results show that the complex stability is governed primarily by the number of sulfur donor atoms, and the nitrogen atom of the N-phenylpolythiazaalkane derivatives scarcely contributes to the stability of the complexes. The selectivity was observed for most of them. The extraction equilibria of the Ag(I) complexes of N-phenylpolythiazaalkane derivatives were studied and the extraction constants of the extracted complexes determined. Results indicate that the extractability of 1:1 complexes depends on their stability. In liquid membrane transport, all N-phenylpolythiazaalkane derivatives exhibited Ag+ ion selective transportability and the order for the Ag+ ion transport rate was 5 > 2 approximate to 3 > 4 approximate to 6 much greater than 1.

In order to evaluate the metal ion recognition properties of these compounds, the following behaviors were examined: proton dissociation, metal ion complexation, metal ion extraction, and metal ion transport through a liquid membrane containing the compound. First, all of the hydrazone derivatives exhibited a similar proton dissociation constants and a silver ion selective complexation behavior in a 1,4-dioxane-water solution. The blue shifts of the absorption spectra were caused by complexation of the hydrazone derivatives with silver ion. The complexing ability is mainly dependent on the number of sulfur atoms in the molecule. Secondly, tetrathiazaalkane hydrazone derivatives exhibited high selectivity for silver ion in the solvent extraction of some heavy metal ions. Drastic red shifts of the absorption spectra of the organic phase were observed in the extraction of silver ion with tetrathiazaalkane hydrazone derivatives. Acyclic tetrathiazaalkane hydrazone derivative extracted silver ion most efficiently. Thirdly, tetrathiazaalkane hydrazone derivatives exhibited effective uphill silver ion transport ability. Especially, a rapid and selective transport of silver ion was observed for an acyclic tetrathiazaalkane analog through liquid membranes.

In the extraction of silver nitrate from aqueous acidic and basic phases, interestingly, the absorption maxima of the organic phases containing the chromoionophores in the visible absorption region shifted to shorter and longer wavelengths, respectively, Among the chromoionophores used here, the acyclic tetrathiazaalkane hydrazone 4b extracted Ag+ most effectively from an aqueous phase into a 1,2-dichloroethane phase under all the extraction conditions studied, A linear calibration graph up to 5.5 x 10(-5) mol dm(-3) Ag+ in the aqueous neutral phase was obtained spectrophotometrically by using the acyclic tetrathiazaalkane hydrazone 4b and the determination of Ag+ in a silver solder sample was achieved from the calibration graph.

The extractabilities (extraction constants, K-ex) fdr Ag+ decreased in the order: 7,16-diphenyltetrathia-7,16-diaza-18-crow-6 (3) (log K-ex=1.18+/-0.13)>13-phenyltetrathia-13-aza-15-crown-5 (2) (0.75+/-0.09)>7-phenyldithia-7-aza-9-crown-3 (1) (-0.47+/-0.06)>13, 16-diphenyltetrathia-13,16-diaza-18-crown-6 (4) (-0.62+/-0.16).

    H SAKAMOTO, S ITO, M OTOMO

    CHEMISTRY LETTERS ( CHEMICAL SOC JAPAN )  ( 1 ) 37 - 38   1995.01

     View Summary

    Nine acyclic polyethers incorporating oxygen, nitrogen and/or sulfur atoms were synthesized, which possess two heterocyclic groups at both ends of an ether chain, and metal ion extractabilities of these compounds were estimated using 1,2- dichloroethane - H2O system. On the solvent extraction of some transition metal ions as the nitrates, Ag+, Cu+ and Hg2+ were more effectively extracted with most of the reagents than the other metal ions. Addition of picrate ion into the aqueous phase of AgNO3 increased Ag+ extractability remarkably.

    BULLETIN OF THE CHEMICAL SOCIETY OF JAPAN ( CHEMICAL SOC JAPAN )  66 ( 10 ) 2907 - 2914   1993.10

     View Summary

    Four types of benzo-15-crown-5 and benzo-18-crown-6 derivatives bearing a substituted hydrazone moiety as a proton-dissociable chromogenic group were synthesized and the solvent extraction behaviors of these compounds for alkali metal ions were evaluated spectrophotometrically. Benzo-15-crown-5 and -18-crown-6 hydrazones with 2,4-dinitro-6-(trifluoromethyl)phenyl or 2,6-dinitro-4-(trifluoromethyl)phenyl groups extracted alkali metal ions predominantly as 2:1 and 1:1 (crown ether: metal ion) complexes, respectively, from an aqueous alkaline solution into 1,2-dichloroethane and these ligands exhibited high K+-selectivity. The composition of the extracted species and the K+-selectivity depended on the polarity of the extraction solvent used. In particular, 2:2 complexes of several alkali metal ions with benzo-15-crown-5 and -18-crown-6 hydrazones bearing a 2,4-dinitro-6-(trifluoromethyl)phenyl group were readily extracted from an aqueous solution into chloroform.

    ANALYTICAL SCIENCES ( JAPAN SOC ANALYTICAL CHEM )  7 ( 6 ) 919 - 924   1991.12

     View Summary

    The extraction of cyanate, thiocyanate or selenocyanate ions with the copper(II) complex of di-2-pyridylmethanone 2-quinolylhydrazone (DPQH) into benzene has been investigated spectrophotometrically at 25-degrees-C and mu = 0.1. Copper(II) reacts with DPQH in a weakly acidic solution to form a dispositively charged mono complex (Cu(HL)2+) with the formation constant of log beta-Cu(HL) = 9.47. This complex undergoes deprotonation to a highly colored CuL+ species in the higher pH range, the proton dissociation constant having been determined to be pK(ac) = 4.53. In the presence of the above-mentioned anions both complex species can be extracted into benzene as a highly colored ternary complex, Cu(L)A (A = NCO-, NCS- or NCSe-). The extraction constant, defined as K(ex) = [Cu(L)A]o/[Cu(L)+][A-] (the subscript (o) denotes the organic phase), is found to be 4.96 for NCO-, 6.15 for NCS- and 5.56 for NCSe- in logarithmic units. On the basis of the above observations, a sensitive spectrophotometric method for the determination of up to 3 x 10(-5) M of the anions has been developed by measuring the absorbance of the organic phase at 540 nm.

    ANALYTICAL SCIENCES ( JAPAN SOC ANALYTICAL CHEMISTRY )  7 ( 7(Supplement) ) 21 - 24   1991

     View Summary

    Solvent extraxction of nickel(II) complexes with five heterocyclic hydrazones(containing pyridine- or/and quinoline-nitrogen atoms as the coordinating sites) into chloroform or benzene has been studied kinetically at 25 degrees C and mu = 0 1 by means ofa spectrophotometric method. The kinetics of extraction of nickel(II) ion is first order in each of the aqueous nickel(II) concentration and the hydrazone concentration in the organic phase. The observed second-order rate constant, k(obs), - pH profiles suggest three rate-determining steps to be considered in the aqueous phase: Ni2+ + H2L+ ->, Ni2+ + HL -> and Ni(OH)(+) + HL -> The rate constant for the formation of 1:1 complex with 2-pyridylmethanone 2-pyridylhydrazone (PAPH) was consistent with those for bipyridine and terpyridine. Replacement of pyridyl group by quinolyl group affects the distribution constant(K-d) of the ligand between the two phases rather than the rate constants for rate-determining steps, and consequently the difference in k(obs) is chiefly governed by K-d. The influence of the structure of ligands on the rate constants is also discussed.

     View Summary

    Eight 14-crown-4 derivatives carrying two, three or four bulky substituents have been synthesized in anattempt to improve the selectivity of the parent macrocycles for Li+. The bulky lipophilic substituents are expected to suppress the formation of stable 2: 1 (crown ether/cation) complexes with Na+. The selectivity for Li+ against Na+ increased with bulkiness of the substituents up to bearing two benzyl groups and then leveled off with bulkier substituents. In the cases of multi-substituted 14-crown-4 derivatives, however, there was a pronounced drop in the Li+ preference over the other cations except for Na+, compared to dibenzyl and dodecyl methyl-14-crown-4. © 1990, The Japan Society for Analytical Chemistry.

    Nippon Kagaku Kaishi   1987 ( 3 ) 277 - 282   1987

     View Summary

    Lipophilic bis(monoaza-12-crown-4) [1a], bis(rnonoaza-15-crown-5) [1b], bis (12-crown-4)[2], and corresponding monocyclic monoazacrown ethers (3a) and [3b] were applied to neutral carriers of ion-selective electrodes for sodium and potassium ions. The potential response of these electrodes towards sodium and potassium ions were found to be dependent on pH of the solution. The ion-selective electrodes based on [la] and [lb] showed Nernstian or near-Nernstian response in wide activity ranges of the metal ions in the solution of high pH, showing prominent selectivities for sodium and potassium ions, respectively (KNaKPOT for [1a] electrode: 8.9×l0-3, KNaKPOT for [1b] electrode: 9.1×l0-3, at pH 13). The bis(monoazacrown ether)s are superior to the corresponding monocyclic analogs, [3a] and [3b], significantly as the neutral carriers of the sodium and potassium ion-selective electrodes. In spite of the similar bis (crown ether) structure, [2] is inferior to [1a] in the sodium selectivity. The excellent sodium selectivity of the electrode based on [1a] was not affected much by the parameter of ion-selective membrane such as variation of plasticizer, neutral carrier concentration, and addition of lipophilic salt. © 1987, The Chemical Society of Japan.
