As a new target following xerographic photoreceptor in the research of organic opto-electronic materials, photorefractive polymers have been investigated focusing on the PVK/TNF photoconductive polymer. The serious problem of thermal instability of the PVK-based PR polymer reported by Arizona Univ. group has been solved by replacing EtCz added as a hole transportable plasticizer with BisCzPro (dimeric compound) of their mixture. We have succeeded in fabricating a highly stabel photorefractive polymeric system and high-speed response of less than 100 ms has been achieved, which seems to promise a future application for the real-time hologram. This paper will describe the molecular design for high performance and demonstrate the state-of-arts in real-time hologram using the present photorefractive polymer
