摘要：

Poly(4-cyano-4'-methacryloyloxyazobenzene) displayed a slow E-to-Z photoisomerization rate and a low Z-isomer content at a photostationary state in a film. Linearly polarized 436 nn light irradiation resulted in the gadual generation of dichroism due to the reorientation of the azobenzene chromophores. The photodichroism was enhanced markedly by heating the film and not deteriorated even at 240 degrees C. Discussion was made on the thermally enhanced photodichroism of the polymer with p-cyanoazobenzene side chains in respect to its semi-crystallinity.
