Marder et a/./ describe the synthesis of several new photorefractive polymers, which are composed of a new type of nonlinear optical chromophore attached to conjugated polymer, poly(p-phenylene-thiophene). 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 at a field of 50 V/ m and a diffraction efficiency of 68% at a field of 46 V/ m for polymer PI were obtained, which are among the best values for fully functionalized PR polymers to date.
