Chemical structures of the polymerizable liquid crystals and the perylene. Tg is the glass transition temperature, Cr is crystal, N is nematic phase, and 1 is isotropic liquid. 1 is a monotropic liquid crystal which forms nematic phase when the material is heated to form the isotropic liquid and then cooled down to the specified temperature.
