ABSTRACT
Abstract-Polyimides with significantly enhanced photoconductivity were synthesized by the po lymerization of a rhenium tricarbonyl complex with various aromatic dianhydrides. The rhenium complex acted as the photosensitizer in the visible region. Electronic absorption spectra of the polymers showed a very strong intramolecular charge transfer transition and a large photocurrent re sponse was observed. The photocharge generation process was studied by simulating the experimen tal quantum yield with the Onsager’s theory, which indicated that the primary yield and the thermalization distance were of the order of 10“4 and 1.7 nm, respectively.
