摘要： 设计出一种高荧光量子效率的发光齐聚物——4,4'-二羟基苯乙烯基-4,4'-联苯, 并以此作为A2单体, 以季戊四醇的对甲基苯磺酸酯为B4单体, 通过A2+B4的路线, 合成出一种结构新颖的部分共轭型超支化发光聚合物. 该聚合物呈理想的三维结构, 分子中非共轭间隔链段的引入不仅能改善发光聚合物的溶解度和加工性, 还在一定程度上阻止了荧光基团之间的重叠, 阻止激子系间窜越等非辐射复合的发生, 减小了分子间或分子内生成激基缔合物或复合物的几率, 从而提高了量子效率.

关键词: 超支化聚合物, 发光, 激基缔合物

Abstract: A partial conjugated hyperbranched light-emitting polymer was obtained by copolymerization of a fluorescent A2 monomer and a non-conjugated B4 monomer. The polymer displays a good thermal stability compared with its linear counterparts, and a good solubility, controllable luminescent properties compared with full-conjugated light-emitting polymers.

Key words: Hyperbranched polymer, Luminescence, Excimer
