    N-Phenylphenothiazine derivatives extended with various aryl groups were designed and synthesized. These derivatives have bent conformation in crystal and exhibit high solubility. Radical cations obtained by one-electron oxidation of these derivatives gave stable radical cations in solution and showed absorption in the near-infrared region. A radical cation was isolated as a stable salt, which exhibited heat resistance up to around 200 °C. A design strategy for radical cation-based near-infrared absorbing dyes, which are easily oxidized and stable not only as a solution but in solid form, is described.

  • Substituent Control of Near-Infrared Absorption of Triphenylamine Radical Cation Reviewed

    Five triphenyltriphenylamines with various substituents were investigated as precursors for near-infrared absorbing materials. Cyclic voltammetry (CV) studies showed that they all give stable radical cations in solution. The radical cations obtained by one-electron chemical oxidation of these compounds show strong absorption in the near-infrared region, and the position of the absorption is strongly influenced by the substituent. DFT (density functional theory) calculations suggest that the introduction of stronger electron-donating substituents would result in a smaller HOMO–SOMO energy gap and thus a larger long wavelength shift, which is consistent with the experimental results. On the other hand, strong electron-withdrawing substituents increase the HOMO–SOMO energy gap, resulting in a short wavelength shift. The position of the near-infrared absorption peak of the triphenylamine radical cation can be controlled to the longer or shorter wavelength direction depending on the substituent. A molecular design of near-infrared absorbing dyes utilizing the electronic effects of substituents is described.

    A ligand, 4-methoxy-4 ',4 ''-bis[N,N-bis(2-pyridylmethyl) aminomethyl]triphenyl-amine, and its palladium and copper dinuclear complexes were designed and prepared in order to examine intramolecular interactions between an organic cation radical and the metal ion. Novel NMR techniques, COSY and NOESY, were applied to the palladium complex to examine its conformation in solution. The palladium complex was found to prefer a folded conformation at ambient temperature, indicating the occurrence of intramolecular stacking interaction. CV measurements of the copper complex showed reversible Cu-I/Cu-II and TPA/TPA(+) redox couples. The spin-spin interaction in the radical pendant copper complex generated upon one electron oxidation of the copper complex was examined by cw-ESR measurements. (c) 2006 Elsevier Ltd.

    The Pd(II) complexes of new 2N1O-donor ligands containing a pendent indole, 3-[N-2-pyridylmethyl-N-2-hydroxy-3,5-di(tert-butyl)benzylamino]ethylindole (Htbu-iepp), 1-methyl-3-[N-2-pyridylmethyl-N-2-hydroxy-3,5-di(tert-butyl)benzylamino]ethylindole (Htbu-miepp), 3-[N-2-pyridylmethyl-N-2-hydroxy-3,5-di(tert-butyl)benzylamino]methylindole (Htbu-impp), and 3- (N-2-pyridylmethyl-N-4-hydroxybenzylamino)ethylindole (Hp-iepp) (H denotes a dissociable proton), were synthesized, and the structures of [Pd(tbu-iepp)Cl] (1a), [Pd(tbu-iepp-c)Cl] (1b), [Pd(tbu-miepp)Ci] (3), and [Pd(p-iepp-c)Cl] (4) (tbu-iepp-c and p-iepp-c denote tbu-iepp and p-iepp bound to Pd(II) through a carbon atom, respectively) were determined by X-ray analysis. Complexes la prepared in CH2Cl2/CH3CN and 3 prepared in CH3CN have a pyridine nitrogen, an amine nitrogen, a phenolate oxygen, and a chloride ion in the coordination plane. Complex 1b prepared in CH3CN has the same composition as 1 a and was revealed to have the C2 atom of the indole ring bound to Pd(II) with the Pd(II)-C2 distance of 1.973(2) Angstrom. The same Pd(II)-indole C2 bonding was revealed for 4. Interconversion between 1a and 1b was observed for their solutions, the equilibrium being dependent on the solvent used. Reaction of 1b and 4 with 1 equiv of Ce(IV) in DMF gave the corresponding one-electron-oxidized species, which exhibited an ESR signal at g = 2.004 and an absorption peak at similar to550 nm, indicating the formation of the Pd(II)-indole pi-cation radical species. The half-lite, t(1/2), of the indole radical species at room temperature was calculated to be 20 s (k(obs) = 3.5 x 10(-2) s(-1)) for 1b. The cyclic voltammogram for 1b in DMF gave two irreversible oxidation peaks at E-pa = 0.68 and 0.80 V (vs Ag/AgCl), which were ascribed to the oxidation processes of the coordinated indole and phenolate moieties, respectively.

    廃棄セルロース系繊維をバイオ発酵して得られる希薄エタノール水溶液(約10wt%)を膜分離技術でエタノールを選択的透過濃縮する高分子膜をポリジメチールシロキサン(PDMS)とテトラエトキシシラン(TEOS)から成るPDMS/TEOS架橋膜を成膜条件を種々変えて成膜した。得られたPDMS/TEOS膜を我々が開発した温度差制御気化浸透法(TDEV)法に適用し、エタノール濃縮性能を種々の透過条件下で検討した結果、PDMS濃度30wt%、PDMS/TEOSモル比0.5から成膜した膜を10wt%エタノール水溶液 (40oC) を供給液にし、膜周辺温度を0oCとしたTDEV法に適用した時、透過速度1.2kg/m2h、透過液中エタノール濃度63wt%の結果を得た。また、63wt%の透過液を供給液にし、同一透過条件下で透過分離特性を検討すると、透過速度3.5kg/m2h、透過液濃度80wt%の結果を得、PDMS/TEOS膜をTDEV法に適用することは意義深いことを確認した。
    一方、上記のPDMS/TEOS膜はエタノール選択透過性を示す疎水性膜であるが、有機溶媒中から微量の水を脱水除去するには親水性膜が有効である。そこで、親水性膜の代表的な膜としてキトサン膜に着目し、多孔質キトサン膜によるジメチルスルホオキシド(DMSO)中の脱水除去をTDEV法で検討した。この場合には、高い透過速度で水がキトサン膜を選択的に透過して除去され、透過セル系内に脱水されたDMSOが残る。上述の疎水性膜によるエタノールの選択的透過濃縮と親水性膜による脱水除去のTDEV法での透過分離機構の解明から、混合溶液中の各成分分子の氷点と膜との親和性の相違を考慮することで、どのような混合物であっても高い透過速度で分離が可能であることを明らかにできた。

    We have studied metal complexes to use for obtaining valuable amino acids from mixtures of stereoisomers, which are prepared by economical synthetic methods. It was revealed that a copper complex containing a tridentate derivative of L-proline analog can bind more strongly to amino acids having a specific configuration than those having the other configuration.

    ポリメチルメタクリレート(PMMA)とポリジメチルシロキサン(PDMS)からなるグラフト共重合体(PMMA-gPDMS)膜にイオン液体である1-Allyl-3-butyl imidazolium bis(trirluoro methanesulfonyl)imide([ABIM]TFSI)[ABIM]TFSIを含有させた膜を用いて,浸透気化法による水中に微量に溶存するVOCsの選択的透過除去における膜構造―透過分離特性―透過分離機構の関係を明らかにした。
    [ABIM]TFSI含有量の異なるPMMA-gPDMS膜を用いて,希薄ベンゼン水溶液を透過すると,いずれの[ABIM]TFSI含有率においても透過液中のベンゼン濃度は供給液濃度よりも著しく高い値を示し,これらの膜が優れたベンゼン選択透過膜であることを明らかにした。また,[ABIM]TFSI含有率の増加に伴い,[ABIM]TFSI含有PMMA-gPDMS膜のベンゼン選択性および透過性が向上した。これは,膜内に含有された[ABIM]TFSIとベンゼンとの親和性の向上に依存していた。[ABIM]TFSI含有PMMA-gPDMS膜のガラス転移温度(Tg)に及ぼす[ABIM]TFSI含有率の影響について検討した結果,PMMA相におけるTgは[ABIM]TFSI含有率の増加に伴い著しく減少したが,PDMS相におけるTgは[ABIM]TFSI含有率に依存せず,ほとんど変化は見られなかった。この結果は,PMMA-gPDMS共重合体膜内への[ABIM]TFSIの含有がPDMS相よりもPMMA相に大きく影響を与えていることを示しており,[ABIM]TFSIは主にPMMA相中に存在していることを明らかにした。
