Abstract

A dye dispersed photoconductor has been developed using (oligo phenylene sulfide)-polyimide (OPS-PI) as a matrix polymer. The OPS-PI was comprised of a series of thiophenylene moieties, -C6H4S-, and imide rings, having a novel carrier transport ability. The dispersed photoconductor showed a panchromatic photosensitivity in the wide wavelength 400-900 nm region, which resulted from the carrier generation of the OPS-PI in the wavelength nm region and from that of the dyes, metal-free phthalocyanines, in the wavelength 600-900 nm region. A model of sensitizing the OPS-PI by means of dye dispersion is presented based both on the electronic structural study of the crystalline OPS-PI and on the optical and photoconductive studies of the copolymers derived from the OPS-PI and its modified polyimide. According to our proposed model, the optimum of the dye content in the OPS-PI for enhancing photosensitivity has been determined in the range not to destroy the carrier transport paths.
