This paper reports our studies of the preparation and characterization of novel xerographic photoreceptors with sol-gel based silsesquioxane polymeric charge transport layers. Photoreceptors have been prepared where the sol-gel layer is the sole transport layer (CTL) directly contacting the near-IR-absorbing charge generation layer (CGL). The sol-gel layers are novel in that they incorporate charge transport moieties covalently linked in a co-polymer, which is subsequently networked into the silsesquioxane matrix via the sol-gel process. We have investigated the photogeneration efficiencies of these photoreceptors and their dependence on sol-gel composition.
