| Abstract: | The UV-induced trans/cis photoisomerization and the thermal back-isomeriZation were investigated for the azo monomer and copolymer in solution and copolymer in solid film and correlated with the structures of the compounds. The results demonstrate that both solutions of the azo monomer and the copolymer and the condensed film of the copolymer can undergo photoisomerization and thermal back-isomerization, and the environments of the azo group are mainly responsible for the above photochemical process. |
