Outline of Final Research Achievements

The development of new pi-conjugated system for single-molecular electronics has been extensively investigated. Especially, we have focused on the realization of single-molecular photovoltaics. To accomplish this purpose, the introduction of hole-transporting, electron-transporting, and anchor units is essential. Thus, we have designed and synthesized new thiophene-based pi-conjugated molecules bearing fullerene and a thiol group at the terminal positions. Their electronic properties are investigated by photophysical and electrochemical measurements.
