Development of novel π-electron systems for electronic applications

研究の背景 Background


π-Conjugated compounds have unique electronic, optical, and redox properties. The number of π-conjugated systems created in recent years has increased in a geometric progression, and their structure–property relationships have been unambiguously elucidated. Towards a next research stage for the practical application of “function of π-electron”, development of novel π-conjugated systems for use in advanced electronic materials has become an active area of research.

研究の目標 Outcome


The main objective of our research is to develop novel π-conjugated systems for the realization of organic electronics and single-molecule electronics and to establish guidelines for the design of such materials. Our recent subject is development of semiconducting materials for organic field-effect transistors (OFETs) and organic photovoltaics (OPVs) as well as essential components for the construction of molecular-scale electronic devices.
