Paper Abstract

A novel photoresponsive polymer containing bisazo chromophores have been synthesized for comparative study with monoazo polymer. Since the bisazo structure has an extended Π-conjugation electronic system, it is expected to have large intrinsic molecular birefringence that can realize large macroscopic photoinduced birefringence (ΔnPI) via photoinduced molecular re-orientation process of bisazo molecules. As a result, it was found that the large value of ΔnPI (0.17) could be obtained by using bisazo polymer at 514.5nm excitation with 1.0W/cm2.
