Kazuyoshi Tanaka,Tohru Sato,Tokio Yamabe,Kenji Okahara,Kunio Uchida,Motoo Yumura,Hiroyuki Niino,Satoshi Ohshima,Yasunori Kuriki,Kiyoshi Yase,Fumikazu Ikazaki +10 more
TL;DR: In this article, the electronic properties of purified carbon nanotubes were examined based on the electron spin resonance (ESR) spectroscopy and it was shown that the purified nanotube is a clean semiconductor almost without magnetic impurity and is doping inactive.
Journal ArticleDOI

TL;DR: In order to understand the relationship between the molecular orientation and optical properties of oligophenylenevinylene film, oriented thin films of 1,4-di(p-methoxystyryl)benzene (DSB-1) and 2,5-dimethoxybenzenes (DSB-2) were fabricated on a potassium bromide (KBr) (001) surface by the vacuum-evaporation method as discussed by the authors.
Journal ArticleDOI
Structural study on cast films of C60 derivatives with long alkyl chains
Masayuki Chikamatsu,Takeshi Hanada,Yuji Yoshida,Nobutaka Tanigaki,Kiyoshi Yase,Hiroyuki Nishikawa,Takeshi Kodama,Isao Ikemoto,Koichi Kikuchi +8 more
TL;DR: In this paper, cast films of C60 derivatives with a long alkyl chain were prepared and characterized, and high ordered reflection peaks were observed in cast films, where the two-dimensional layer structure was more stabilized.
Journal ArticleDOI
Side-Chain Effects on Friction-Transferred Polymer Orientation
Shuichi Nagamatsu,Shuichi Nagamatsu,Masahiro Misaki,Tatsumi Kimura,Yuji Yoshida,Reiko Azumi,Nobutaka Tanigaki,Kiyoshi Yase +7 more
TL;DR: In this paper, the effects of substituted side-chains of poly(2,5-dialkoxy-1,4-phenylenevinylene) derivatives (PPV) on polymer orientation have been studied using polarized optical spectroscopy and synchrotron-sourced grazing incidence X-ray diffraction (GIXD) analysis.
Journal ArticleDOI
Epitaxial crystal growth of poly(p-oxybenzoate) on highly oriented poly(tetrafluoroethylene) with various support substrates
TL;DR: In this article, the molecular chains of poly(p-oxybenzoate) (POBA) were found to be highly oriented parallel to the PTFE chain direction.
