This paper describes the synthesis and physical study of several new photorefractive (PR) polymers, which are composed of a new type of nonlinear optical (NLO) chromophore attached onto conjugated poly(p-phenylene-thiophene)s. Since the NLO chromophore is labile in many reaction conditions, the Stille coupling reaction was used to prepare these polymers. The resulting polymers exhibit high PR performances. An optical gain coefficient of 158 cm(-1) at a field of 50 V/mum and a diffraction efficiency of 68% at a field of 46 V/mum for polymer P1 were obtained, which are among the best values for fully functionalized PR polymers to date.
