The anisotropic photoreaction of a copolymer liquid-crystals (CPLC) comprising one co-monomer being anisotropically photo-crosslinkable by linearly polarized (LP)-UV light and the other being insensitive to UV-irradiation is presented. Polarized UV and IR studies suggested a photo-induced alignment of the mesogenic side groups during the LP-UV photoreaction at the LC temperature range of the copolymer. In this paper we reported effect of spacer length on photo-induced alignment of photo-crosslinkable copolymer liquid crystals film.
