Abstract

We synthesized two copolymers bearing photochromic spiropyran dye in the side chain for studying the dynamic properties of their photochromism. The dynamic processes of colorization and decolorization under an excitation light were investigated using the two copolymers. One of the copolymers contains methylmethacrylate (MMA) and methacrylate-spiropyran (MA-spiropyran). The other one contains methacrylate-spiropyran (MA-spiropyran) and methacrylate- chalcone (MA-chalcone) as a comonomer. Investigation of the photosensitivity of the newly synthesized copolymers was carried out by using UV-vis absorption spectroscopy. We observed the photodimerization and photochromic behavior under UV irradiation simultaneously. The effect of photocrosslink on the stability of photochromism was considered from this study.
