was born in Osaka, Japan in 1950. He completed his undergraduate studies in applied chemistry at Kyoto Institute of Technology in 1973 and received his M. S. degree in hydrocarbon chemistry at Kyoto University in 1975. Immediately after this he obtained a research position at the Wireless Research Laboratory of the Matsushita Electric Industrial Co., Ltd. and subsequently a research position at the Central Research Laboratories in Matsushita. From 1985–1987 he stayed in the group of Professor A. J. Heeger at the University of California, Santa Barbara. He obtained his Ph.D. degree in hydrocarbon chemistry at Kyoto University in 1988. He joined the Quantum Wave Project, Exploratory Research for Advanced Technology (ERATO), Research Development Corporation of Japan (JRDC) in 1989. From October 1, 1993 he has been working at the Matsushita Research Institute. His major research activities are directed to the synthesis and electronic properties of specialty organic and polymer materials.

The crystal structures and morphologies of oligothiophenes, in the form of both single crystals and thin films, are reviewed and compared with those of other oligomers and conducting polymers. The “herringbone” structure emerges as a pivotal motif, in particular for charge transport. Although further research is necessary to elucidate the charge transport mechanism, this does not prevent the structural and electronic features of conducting oligomers being exploited in electronic devices such as FETs and LEDs.
