中文摘要：
通过Suzuki偶合反应合成了一系列胺烷基侧链取代的基于三苯胺和芴的共轭聚合物聚[4-（N，N-二甲基胺丙氧基）苯-4，4＇-二苯胺-9，9-二辛基芴-4，7-二噻吩-2-基-2，1，3-苯并噻二唑]（PFTD），并对其化学结构和光电性能进行了表征．末端胺基的存在提高了此类聚合物作为发光层应用于聚合物电致发光器件的性能（采用高功函数的金属铝作为阴极时）．结构为ITO／PVK／PFTD-5（DBT摩尔分数为5％时的聚合物）／Al的器件最大电致发射峰位于647nm，最大外量子效率达到了1．24％．
英文摘要：
A series of amino-alkyl substituted, triphenylamin and fluorene-based red-emitting polymers with different feed ratios of 4,7-di-2-thienyl-2,1,3-benzothiadiazole （DBT） component were synthesized by Suzuki coupling reaction. The chemical structures of these polymers were eonfirmed and the optoelectronic properties of them were investigated. PLEDs using these polymers as emitting-layer with high work function metal, Al, as cathode exhibited fairly good devices＇ performance. The device with structure of ITO/PVK/PFT-DBT-5/Al show emission peak at 647 nm, and the maximum external quantum efficiency reaehed 1.24%.
