Synthesis and Structures of Sterically Encumbered Group 14 Monolithio Compounds and Unexpected Differences in Their Reactivity

Lucian-Cristian Pop, Nobuaki Kurokawa, Hiroaki Ebata, Katsuya Tomizawa, Tomoyuki Tajima, Masaichi Saito

EUROPEAN JOURNAL OF INORGANIC CHEMISTRY ( 43 ) 4969 - 4975 2017年11月

記述言語：英語出版者・発行元：WILEY-V C H VERLAG GMBH

Group 14 monolithio compounds with sterically encumbered terphenyl ligands, ArM14(SiHMe2)(2)Li [M-14 = Si, Ge, Sn; Ar = 2,6-bis(2,6-diisopropylphenyl)phenyl and 2,6-bis(2,4,6-triisopropylphenyl)phenyl], were prepared by transmetalation reactions of ArM14(SiHMe2)(3) with methyllithium, the structures of which were established by X-ray diffraction analysis. The monolithiosilanes and monolithiogermanes reacted with iodomethane and trichlorophosphane to afford the corresponding monomethylated and dichlorophosphane-substituted derivatives, respectively. However, surprisingly, the reactions of monolithiostannanes with iodomethane and trichlorophosphane provided trimethylstannane and trichlorostannane, respectively.

Synthesis of a poly(amidoamine) dendrimer having a 1,10-bis(decyloxy) decane core and its use in fabrication of carbon nanotube/calcium carbonate hybrids through biomimetic mineralization

Shunichi Nishimura, Tomoyuki Tajima, Tatsuki Hasegawa, Tomoaki Tanaka, Yutaka Takaguchi, Yuya Oaki, Hiroaki Imai

CANADIAN JOURNAL OF CHEMISTRY 95 ( 9 ) 935 - 941 2017年9月

A new dendritic dispersant of carbon nanotubes (CNTs) was synthesized and applied for the noncovalent functionalization of single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs). The 1,10-bis(decyloxy) decane core of the poly(amidoamine) dendrimer strongly adhered to the sidewalls of CNTs to form CNT/dendrimer supramolecular nanocomposites having many carboxyl groups (-COOH) on the surface. Then, crystallization of calcium carbonate (CaCO3) by the CO2 diffusion technique in aqueous environments using the CNT/dendrimer supramolecular nanocomposites as scaffolds afforded monodisperse spherical CNT/CaCO3 nanohybrids consisting of CNTs and calcite nanocrystals. The morphologies of the SWCNT/CaCO3 hybrids and MWCNT/CaCO3 hybrids were almost the same.

Ligand Exchange Reaction of (Me4N)(4)[Cd10S4(SPh)(16)] with Diphenyl Diselenide

Tomoyuki Tajima, Shoko Yamamoto, Yuta Sakamoto, Shoji Takagi, Toshitaka Nakaya, Yutaka Takaguchi, Asako Igashira-Kamiyama, Nobuto Yoshinari, Takumi Konno

BULLETIN OF THE CHEMICAL SOCIETY OF JAPAN 90 ( 4 ) 384 - 386 2017年4月

記述言語：英語出版者・発行元：CHEMICAL SOC JAPAN

The reaction of (Me4N)(4)[Cd10S4(SPh)(16)] (1) with diphenyl diselenide (2) in propionitrile afforded a molecular cluster, (Me4N)(4)[Cd10S4(SePh)(16)] (3), the structure of which was determined by X-ray crystallography. Ligand exchange proceeded in a heterogeneous reaction system, and the use of a less polar solvent appeared to be crucial for the synthesis of 3 to prevent degradation of the Cd10S4Se16 cluster core.

SWCNT Photocatalyst for Hydrogen Production from Water upon Photoexcitation of (8,3) SWCNT at 680-nm Light 国際誌

Single-walled carbon nanotubes (SWCNTs) are potentially strong optical absorbers with tunable absorption bands depending on their chiral indices (n, m). Their application for solar energy conversion is difficult because of the large binding energy (> 100 meV) of electron-hole pairs, known as excitons, produced by optical absorption. Recent development of photovoltaic devices based on SWCNTs as light-absorbing components have shown that the creation of heterojunctions by pairing chirality-controlled SWCNTs with C-60 is the key for high power conversion efficiency. In contrast to thin film devices, photocatalytic reactions in a dispersion/solution system triggered by the photoexcitation of SWCNTs have never been reported due to the difficulty of the construction of a well-ordered surface on SWCNTs. Here, we show a clear-cut example of a SWCNT photocatalyst producing H-2 from water. Self-organization of a fullerodendron on the SWCNT core affords water-dispersible coaxial nanowires possessing SWCNT/C-60 heterojunctions, of which a dendron shell can act as support of a co-catalyst for H-2 evolution. Because the band offset between the LUMO levels of (8, 3) SWCNT and C-60 satisfactorily exceeds the exciton binding energy to allow efficient exciton dissociation, the (8, 3) SWCNT/fullerodendron coaxial photocatalyst shows H-2-evolving activity (QY = 0.015) upon 680-nm illumination, which is E-22 absorption of (8, 3) SWCNT.

Self-Assembly and Fluorescence Properties of [60]Fullerene-Pentacene Monoadducts

Kentaro Kubo, Tomoyuki Tajima, Hitoshi Shirai, Takuya Nishihama, Yutaka Takaguchi

CHEMISTRYSELECT 2 ( 8 ) 2452 - 2456 2017年3月

記述言語：英語出版者・発行元：WILEY-V C H VERLAG GMBH

The highly soluble [60]fullerene-pentacene monoadducts 2a and 2b were synthesized by a Diels-Alder reaction between [60]fullerene and pentacene derivatives. The single-crystal X-ray diffraction analysis of 2a revealed an attractive intermolecular interaction between [60]fullerene moiety of one molecule and the pentacene arms of an adjacent molecule, resulting in the formation of head-to-tail dimers in solution. This self-association behavior of 2a and 2b was also observed by (HNMR)-H-1 and fluorescence spectroscopy in chloroform. Both the excitation and emission wavelengths can be modulated via the concentration of 2a and 2b.

Synthesis and Light-absorption Characteristics of Thiophene Derivatives Bearing Ferrocenylthiocarbonyl Groups

Hideaki Miyake, Tomoyuki Tajima, Yutaka Takaguchi

CHEMISTRY LETTERS 46 ( 1 ) 48 - 50 2017年1月

記述言語：英語出版者・発行元：CHEMICAL SOC JAPAN

Thiophene-based dyes bearing two ferrocenylcarbonyl groups were obtained from a short synthesis involving direct arylations of the thiophene rings. A subsequent thionation of the carbonyl groups resulted in the formation of new thiophene-based dyes bearing two ferrocenylthiocarbonyl groups. These dyes absorb in a wide range of the visible spectrum due to their p-p* and d-p* transitions, and show a remarkable red-shift of the absorption band relative to their carbonyl analogues without increasing the molecular size.

Incorporating a TiOx shell in single-walled carbon nanotube/fullerodendron coaxial nanowires: increasing the photocatalytic evolution of H-2 from water under irradiation with visible light

K. Kurniawan, T. Tajima, Y. Kubo, H. Miyake, W. Kurashige, Y. Negishi, Y. Takaguchi

RSC ADVANCES 7 ( 50 ) 31767 - 31770 2017年

記述言語：英語出版者・発行元：ROYAL SOC CHEMISTRY

A custom-tailored single-walled carbon nanotube (SWCNT) photocatalyst with an electron-extracting TiOx shell, i.e., a SWCNT/fullerodendron/TiOx coaxial nanowire, has been fabricated. Due to the presence of the TiOx shell, the SWCNT/fullerodendron/TiOx coaxial nanowire shows an enhanced photocatalytic activity (Phi = 0.47) for the evolution of hydrogen from water under irradiation with visible light (lambda = 450 nm).
