Series of epoxy-based polymers functionalized with methyl-substituted azobenzene chromophores have been designed and synthesized. The polymers synthesized were characterized by the spectroscopic methods and thermal analysis. Surface relief gratings (SRGs) were photofabricated on thin films of the azo polymers by exposure to an interference pattern of coherent Ar + laser beams. The methyl substitution...
Epoxy-based azo polymers with three kinds of backbones, different types of azo chromophores, and selected degrees of functionalization (DFs), were synthesized through a post-polymerization azo-coupling scheme. The T g s of the azo polymers were found to be considerably influenced by the substituents on the 4-positions of the azobenzene units and increased with the increase of the DFs of the...
