Abstract:

In order to improve the stability of photo-isomerization patterning of photo-responsive film based on azobenzene moiety, a new photo-responsive material based on azobenzene moiety with high electrochemical activity was designed and synthesized, named 1,2-bis(4-{[6-(9H-carbazol-9-yl)hexyl]oxy}phenyl)diazene(BHCzAzo) which exhibited a good photo-isomerization ability between trans-configuration and cis-configuration. BHCzAzo was prepared into a highly crosslinked polymer film without any crack or peeling on the surface using electrochemical deposition(ED) method due to the electrochemical activity of carbazole moiety in BHCzAzo. And the stability of the prepared film was enhanced in the result of the compact stacking mode of ED film. The film was irradiated with 355 nm interfering laser beam, and then a periodic pattern of photo-induced surface relief gratings was formed with good morphological surface. The photo-induced pattern was proved to possess high stability using the experiments of being immersed in different common solvent and heated at different temperature. The stability of photo-induced pattern was greatly enhanced by preparing cross-linked film with photo-responsive ability using ED method.

Key words: Azobenzene, Photo-responsive material, Electrochemical deposition, Photo-induced surface patterning
