中文摘要：
通过Suzuki聚合反应合成了一系列以芴-alt-咔唑为主链，铱配合物为侧链的深红色电磷光共轭聚合物．发光器件结构为ITO／PEDOT：PSS／PVK／Copolymer／Ba／Al，基于共聚物PFCzIrNiq—1的器件在电流密度为9．4mA／cm^2时，最大外量子效率为0．23％，最大发射波长为680nm．
英文摘要：
A novel monomer derived from dibromocarbazole with N-grafted with Ir complex by a long alkyl side chain was synthesized. Based on this new monomer, a series of poly （fluorene-ah-carbazole） s which tethered red light-emitting Ir complex as emitting center were synthesized with Suzuki polycondensation. The polymer light-emitting diodes with structure of ITO/PEDOT： PSS/PVK/Copolymer/Ba/Al were prepared based on the resulted copolymers. The copolymer PFCzIrNiq-1 exhibits maximal quantum efficiency of 0. 23% at 9.4 mA/cm^2. The peak emission of the resulted copolymers was at 680 nm, which was among the reported deepest iridium containing red-light-emitting electrophosphorescent polymers.
