Molecular aggregation-induced photocarrier generation in layered organic photoreceptors incorporating azo compounds



The high photosensitivity of azo-compound-based photoreceptors is considered to be due to molecular-aggregation-induced geminate-pair dissociation rather than a photo-induced electron-transfer reaction. Both agregated and non-aggregated carrier-generating materials are employed on order to investigate the mechanism of this process, which has practical implications for the development of electrophotography.
