This study presents the results of formation of grating in polymer liquid crystals (PLCs) containing an azobenzene moiety by means of the photoinduced alignment. Grating was obtained by using two linearly polarized beams interfering on the sample films. On the formation of grating, a remarkable difference was observed between the two materials which are PLCs with ortho-substituted azobenzene and the common azobenzene analogs without substituents. The PLC with substituted azobenzene showed a faster response for the formation of grating. To explore the machanism of the formation of grating in more detail, we investigated the alignment change of the PLCs. In the PLC with the substituted azobenzene, the alignment change took place faster. These results can be explained in terms of the mobility of the ortho-substituted azobenzene moiety and the stability of the LC phase structure.
