Abstract
We have investigated the molecular interface between an azo pigment and an α-phenylstilbene derivative where photocarriers are extrinsically produced from a microscopic viewpoint. From the measurement of the azo-pigment photoluminescence quenching by the α-phenylstilbene derivative, only the molecules that contact with the azo-pigment particles are known to promote generation of the photocarriers. The electron-transfer reaction at the interface for photocarrier generation is proven to occur adiabatically.
