The development and performance of tetraphenyldiaminobiphenyl-based polymer composites with stable video-rate-compatible response times over large exposures is reported (see Figure). The high diffraction efficiency together with an exposure-history independence of the response time described is a significant advance for developing an all-organic photorefractive composite for device applications.
