Photorefractive effect was observed in a new type of polymer comprising several kinds of the substituent dissolved in low-molecular liquid crystals of E7 doped with 2,4,7-trmitro-9-fluorenone (TNF). We synthesized methacrylate copolymers with a cyanophenyl benzoate, a methoxyphenyl benzoate, a nitorophenyl benzoate or a dicyanovinylphenyl benzoate side groups and a carbazoyl ethoxy side group. Photorefractive performance was evaluated by two-beam coupling method.
