The liqud crystals (LCs) monomers 4-(Undecenoic-1-yloxybenzoyloxy)-4’-cyanobenzene e M1 and 5-{4-[4-(4-undecyloxy) biphenyl] -oxycarbonyl} pentanoic acid cholesteryl ester M2 are synthesized. The liquid crystals polymer was synthesized by nematic and chiral LC monomers. The property of the LC materials are detected by POM and DSC. The bandgaps of the LC polymer are influenced by the change of temperature. The effect of temperature on the reflective wavelength is decreased from 513nm to 394nm with temperature increased. The chiral LC polymer is a one dimension photonic materials. The optical and thermal property of the CLCs polymer is controlled by the out field, and widely used for display, smart windows and chiral liquid crystal laser etc.
