摘要

采用Suzuki耦合反应将两个喹啉受体连接在一起成为电子受体（acceptor），通过连接给电子能力不同的给体基团（donor），合成出三个新型的线性二聚体发光材料：BtCzPPQ、DCPPQ和PZPPQ。三个材料均具有良好的刚性、热稳定性（

220 ℃），以及较高的光致发光量子产率（70%以上）。通过对材料轨道分布、热稳定性、光物理性质的表征，分析了分子的刚性、线性长度和给受体基团等结构因素对材料电致发光性能的影响。

Abstract

Three novel linear dimeric luminescent materials， BtCzPPQ， DCPPQ and PZPPQ， were synthesized by linking two quinoline receptors together into an electron acceptor （A） using the Suzuki coupling reaction， and by linking donor groups （D） with different electronic donated moiety. All the three materials have good rigidity， thermal stability （

220 ℃）， and high photoluminescence quantum yields （PLQYs more than 70%）. The effects of structural factors such as the rigidity of molecules， linear length， and the donor group on the electroluminescence properties of the materials were analyzed by characterizing the orbital distribution， thermal stability， and photophysical properties of the materials.
