本工作合成了一组不同组成的聚(苯乙烯-乙烯基苯乙酮)高分子敏化剂,对分子中两组分的含量进行了标定.通过荧光和磷光光谱的研究表明:高分子敏化剂分子中存在着单重态和三重态的能量迁移和 T~*-T~ 湮灭作用.从降冰片二烯光敏异构化为四环烷的反应中发现,苯乙酮摩尔含量为38％的高分子苯乙酮敏化剂具有最大的敏化能力,并对上述诸现象产生的原因进行了分析和讨论. In this work, a series of poly (styrene-vinyl acetophenone) polymer sensitizers with different compositions were synthesized, and the content of the two components in the molecule was calibrated.The results of fluorescence and phosphorescence spectra showed that the polymer The singlet and triplet energy transfer and T ~ * -T ~ annihilation effect exist in the molecule of the agent. From the reaction of isomerization of norbornadiene to tetracycloalkane, the molar content of acetophenone is 38 % Of the polymer acetophenone sensitizer has the greatest sensitization capacity, and the causes of the above phenomena were analyzed and discussed.
