Synthesis of a highly birefringent liquid-crystalline polymer (LCP) containing the azotolane functional group in the mesogenic moiety was investigated. The homogeneously aligned film of the LCP film exhibited a large delta in a wide wavelength range. The photoismerization behavior of the azobenzene moiety in the mesogen in P4TA in toleune was investigated. Results show that the LCP film exhibits rewritability with little photobleaching.
