Photoreactive polymethaclates with methoxycinnamoyloxybiphenyl side group were synthesized to induce a high degree of molecular orientation. The high orientational order of the film was induced by irradiation of linearly polarized ultrabiolet(LPUV) light and subsequent annealing. Three dimensional molecular orientation in the film can be acheived by oblique irradiation with LPUV light. Optical birefringence of the film is controlled to be Δnd > 100nm. In addition, we demonstrate an optical film having reflective properly depending on lhe polarization direction of incident light.
