| Abstract: | Two bifunctional copolymers were synthesized bearing photochromic spiropyran dye in the side chain for studying the dynamic properties of their photochromism. The dynamic processes of colorization under an excitation light were investigated using the two copolymers. One copolymers contained methylmethacrylate (MMA) and methacrylate-spiropyran (MA-spiropyran) as comonomers and other structure was kept methacrylate-spiropyran and methacrylate-chalcone (MA-chalcone). Investigation of the photosensitivity of the newly synthesized copolymers was carried out by using UV-vis absorption spectroscopy. The results showed that the photocrosslink affected on the stability of photochromism. |
| Keywords: | photochromism chalcone spiropyran photocrosslink |
