摘要(Abstract)：

通过迈克尔加成反应合成单体2，7-二溴-9，9-二（丙酸十二氟庚酯）芴（FDFHP），采用Suzuki偶合反应制备不同FDFHP结构单元含量的含氟聚芴（PF8FDFHP）。通过红外光谱、核磁共振氢谱等方法对其结构和性能进行研究。结果表明：含氟侧链的引入能有效提高聚芴的疏水性，对聚合物的HOMO、LUMO能级没有太大的影响，但使得聚芴在440 nm处的荧光发射峰逐渐消失，在500~600 nm出现一个新的荧光发射峰。分析认为这是由于含氟侧链的引入使得聚芴的侧链产生结晶，主链之间堆砌更加致密而产生激基缔合物所致。通过不同浓度含氟聚芴溶液的荧光光谱与聚芴的DSC测试对此作了进一步分析。
