Thin solid films of PMMA doped with donor–acceptor norbornadienes were prepared, and their photochromic properties were examined. The photochromic solid films have absorption at a visible region, and their photochemical decolorization due to valence isomerization proceeded in high quantum yields. They show resistivity for the repeated cycle of the interconversions and no loss in the extinction was observed even after 103 times of cycle of reactions.
掺入了供体-受体降冰片二烯的PMMA薄固体薄膜已经制备完成,并对其光致变色特性进行了研究。光致变色固体薄膜在可见光区域具有吸收特性,其光化学脱色是由于价态异构化引起的,且量子产率很高。它们对反复的相互转换循环表现出电阻率,即使在103次反应循环后,也没有观察到消光损失。
