Journal ArticleDOI
Synthesis of tetrathieno-acene and pentathieno-acene: UV-spectral trend in a homologous series of thieno-acenes
Yasuhiro Mazaki,Keiji Kobayashi +1 more
TL;DR: Tetrathieno-acene was synthesized in this article, and the progressive redshift of the longest wavelength band exhibited an excellent linear correlation with the number of thiophene rings.
Journal ArticleDOI
Polymorphism and electrical conductivity of the organic superconductor (DMET)2AuBr2
Koichi Kikuchi,Yoshiaki Honda,Yoshimitsu Ishikawa,Kazuya Saito,Isao Ikemoto,Keizo Murata,Hiroyuki Anzai,Takehiko Ishiguro,Keiji Kobayashi +8 more
TL;DR: In this article, three kinds of (DMET) 2 AuBr 2 salts were analyzed and the structure analysis of the crystals which were used in the resistivity measurements proved that there were at least two modifications.
Journal ArticleDOI
On Ambient-Pressure Superconductivity in Organic Conductors: Electrical Properties of (DMET)2I3, (DMET)2I2Br and (DMET)2IBr2
Koichi Kikuchi,Keizo Murata,Yoshiaki Honda,T. Namiki,Kazuya Saito,Takehiko Ishiguro,Keiji Kobayashi,Isao Ikemoto +7 more
TL;DR: In this article, superconductivity at ambient pressure in (DMET) 2 I 3 at 0.47 K and in(DMET 2 I 2 Br 2, where DMET is (dimethyl(ethylenedithio)diselenadithiafulvalene), was observed down to 0.59 K (midpoints).
Journal ArticleDOI
Superconductivity in (DMET)2AuCl2 and (DMET)2AuI2
Koichi Kikuchi,Keizo Murata,Yoshiaki Honda,T. Namiki,Kazuya Saito,Hiroyuki Anzai,Keiji Kobayashi,Takehiko Ishiguro,Isao Ikemoto +8 more
TL;DR: In this article, an organic conductor, (DMET) 2 AuCl 2, was found to undergo a superconducting transition at 0.83 K at ambient pressure, but it appeared to undergo metal-insulator transition at about 20 K.
Journal ArticleDOI
Superconductivity and the possibility of semiconductor-metal transition in (DMET)2AuBr2
Koichi Kikuchi,Keizo Murata,Yoshiaki Honda,T. Namiki,Kazuya Saito,Keiji Kobayashi,Tekehiko Ishiguro,Isao Ikemoto +7 more
TL;DR: In this article, an organic conductor, (DMET) 2 AuBrd 2, was found to undergo superconducting transition around 1 K under a pressure of 1.5 kbar.
