Abstract
Azo benzene derivatives are dispersed in a poly(carbonate) or poly(N-vinyl carbazole) matrix, and their photoconductive characteristics are investigated in terms of the structure of azo benzene derivatives and polymer matrix. These azo benzene derivatives are composed of electron donating and accepting parts bridged by azo bonds and are intramolecular charge transfer complexes as determined by UV-Vis spectra and electrochemical measurements. This charge transfer is effective for the increase of photoconduction in these derivative-dispersed poly(carbonate) films. When poly(N-vinyl carbazole) is used as a polymer matrix, photocurrent increases by one order of magnitude in comparison with that in a poly(carbonate) system. The roles of azo derivatives and polymers for photoconduction are discussed with the action spectrum of the photocurrent in these systems.
