3 3 UV-Vis Fig. 2. The change of UV absorbance of polymer solution with UV irradiation, (a)PCEMA, (b)PCEMA/DOD-Ci = 9/1, (b)PCEMA/DOD-Ci = 8/2, (b)PCEMA/DOD-Ci = 7/3. (a)(b) (c) (d)

4 南台化材 4Conclusions 1. 1 H NMR showed that DOD-Ci was synthesized sucessfully and DOD-Ci containing cinnamate groups can produce [2+2] photoaddition reaction upon their exposure to linearly polarized ultraviolet (LP-UV) light. 2. As the weight percent of the DOD-Ci increased from 0 to 30%, the photostability times of the polymer decreased from 30min to 4min.

5 Future work 1.Observe the changes of UV absorbance of polymer solution with UV irradiation by UV-vis spectroscopy, (a)EDCi,(b) PCEMA/EDCi. 2.Observe the changes of UV absorbance of polymer films with UV irradiation by UV-vis spectroscopy. 3.Observe the POM images of liquid crystal cell.
