高分子三重态敏化剂的研究 Ⅲ.高分子苯乙酮敏化过程中能量迁移的研究

A Study on the Polymeric Triplet Sensitizers Ⅲ.A Study on the Energy Migration in Process of Sensitization of Polymeric Acetophenone

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.

A series of vinyl acetophenone-styrene copolymer has been synthesized andcharacterized by NMR.The study of fluorescence and phosphorescence evidenced thepresence of electronic energy migration of singlet and triplet as well as T-T annihila-tion in these polymeric sensitizers.The sensitized conversion of norbornadiene(NBD)toquadricyclane(QDC)indicated that sample containing 38mol%acetophenone monomerpossessed the maximum sensitizing ability.These results were discussed in some details.
