Photoelectric conversion material, film containing the material, photoelectric conversion device, production method thereof, photosensor, imaging device and their use methods

摘要

An organic compound and a photoelectric conversion device containing the organic compound are disclosed. The organic compound and device realize high photoelectric conversion efficiency, low dark current and high-speed responsivity. It has been found that when this organic compound and an n-type semiconductor are used in combination, high-speed responsivity can be realized while maintaining high heat resistance, an aspect of which has not been seen when the connection part between a donor part and an acceptor part is a phenylene group.
