    • Tetsuo Otsubo was born in Osaka, Japan in 1942, and received a B.Sc. (1966) and an M.Sc. (1968) in organic chemistry from Osaka University under the guidance of Prof. Y. Yukawa. He started his academic career as a research associate at the same University, where he studied cyclophane chemistry with Prof. S. Misumi and received a Ph.D. form Osaka University in 1972. He worked at the University of Oregon as a postdoctoral fellow with Prof. V. Boekelheide from 1974 through 1976. In 1979 he joined the faculty of Hiroshima University, where he has been promoted to Associate Professor (1980) and Full Professor (1992). His current research interests focus on the design and synthesis of novel electron donors and acceptors which from conducting organic materials. He is the author of more than 170 publications.

Abstract

Organic conductors based on new classes of dimeric TTFs (e.g., see figure) are reviewed. The complexes have structures in some cases which are determined by inter-TTF transannular interactions, leading to stretched, folded, and sandwich arrangements. These multi-TTF materials have potential applications in the development of molecular electronic devices based on multi-stage redox systems.
