The multi-bilayered films were found to reflect a light of specific wavelength. Photo-responsive multi-bilayered film consisting of azobenzene polymer liquid crystals and polyvinyl alcohol were showed the reversible change in the reflection intensity by irradiation with visible and UV light. In this study, effects of azobenzene structure to optical properties of multi-bilayered films were investigated. The change in reflection intensity was strongly dependent on the number of methylene spacer of azobenzene side group with acrylate polymer main chain. In addition, the response speed of change in reflection intensity will be discussed.
