摘要: 本文研究了PED偶氮化合物在聚甲基丙烯酸甲酯固体介质中的光化学顺反异构化反应。对此种体系在π,π*和n,π*激发条件下光化学顺反异构化的量子产率、光稳态组成以及所在聚合物体系中的自由体积分布等的测定方法和原理进行了详细的介绍。这些方法对其它类似的光致变色体系同样也是适用的。

Abstract: The cis-trans photoisomerization of phenyl-(estta-17 β-ol-3)-diazene (P E D) in polymethyl methacrylate film was investigated. Measurement and evaluation principle and methodology of quantum yield, composition of photostationary state, free volume distribution of the polymer bulk and so on were introduced in detail for cis-trans photoisomerizations in such solid matrix under π, π* or n,π* excitations. These analysis should also be applicable to other similar photochromic system.
