新型侧链型聚芴类农膜转光剂的合成及其性能研究

Synthesis and Properties of Novel Light-Conversion Agent Based on Side-Chain Polyfluorenes

报道了两种新型侧链型聚芴,聚(9,9-二丁基芴乙烯)(PBF)以及(9,9-二丁基芴乙烯)共聚(9-乙烯基咔唑)(PCBF),并对它们的分子量、紫外光谱、荧光光谱、核磁共振氢谱、分子结构和性能等方面进行了研究.结果显示,合成的两种产物均能够强烈地吸收紫外线并发射出蓝光,因此可能成为合适的高分子转光剂材料.

Two kinds of novel side-chain polyfluorenes named poly（9,9-dibutyl-vinylfluorene）（PBF）and poly（9,9-dibutyl-vinylfluorene）-co-（9-vinylcarbazole）（PCBF）were reported.The structures and properties of the polymers had been studied by NMR, UV-Vis, PL and gel permeation chromatography.The results showed that our products could absorb UV light strongly and emit blue light,so they should be proper candidates of macromolecular light-conversion agents.
