Abstract

Formation of gratings by means of the photoinduced alignment change of polymer liquid crystals (PLCs) has been explored in a glassy state. To obtain high diffraction efficiency (η), we synthesized highly birefringent PLCs containing an azobenzene group directly connected with a tolane moiety (3ATm), in which the alkyl spacer length (CHa)m was varied as m = 6, 9 and 12. It was found that the values of birefringence in all the PLCs were about 0.4. The behaviors of the photoinduced alignment change and the formation of gratings were found to be dependent on the alkyl spacer length of 3ATm.
