摘要

A photoresponsive poly(methylmethacrylate/azobenzene) copolymer was synthesized through the copolymerization of methylmethacrylate (MMA) with 6-[4-(4-dimethylaminophenylazo)phenoxy]-hexyl methacrylate (Azo-monomer) to see the effect of UV illumination on the formation of honeycomb-patterned films fabricated by casting the copolymer solution under humid conditions. The synthesized copolymer was characterized by Fourier transform infrared, UV-vis, and nuclear magnetic resonance spectroscopy. The honeycomb-patterned films obtained by UV illumination showed more highly ordered films. It is due to a photo-switched isomerization of the azobenzene component in the PMMA-Azo copolymer from trans- to cis-isomer, which induces the amphiphilicity of the copolymer solution by increased dipole moment.
