| 摘 要： | 用Suzuki缩聚反应制备了一系列新型咔唑-吡啶共轭主链上含有金属铱配合物单元的共聚物. 共聚物发光器件结构为ITO/PEDOT:PSS/polymer＋PBD (w＝30%)/CsF/Al 氧化铟锡/苯磺酸掺杂聚乙烯基二氧噻吩/聚合物＋2,4-二苯-5-4-叔丁基苯-1,3,4-恶二唑(w＝30%)/氟化铯/铝]. 基于共聚物PCzPyIrMppy2的器件在电流密度为20.8 mA/cm2时, 最大外量子效率和流明效率分别达到4.1%和6.1 cd/A. 在电流密度200 mA/cm2时, 器件的最大外量子效率和流明效率仍分别达到3.2%和4.8 cd/A, 器件的发光的最大波长位于570 nm, 最大亮度达到13251 cd/m2. 研究结果表明, 在共轭聚合物主链上引入螯合金属铱配合单元是实现高效、稳定的电致磷光器件的有效方法之一.

| Abstract: | A series of novel poly(carbazole-co-pyridine)s conjugated with copolymerized chelated Ir complexes in the main chain were synthesized by Suzuki polycondensation. Based on such copolymers, the electroluminescent devices were fabricated with configuration of ITO/PEDOT:PSS/polymer+PBD (w=30%)/ CsF/Al. The best device performances were achieved based on copolymer PCzPyIrMppy2, which showed the maximal quantum efficiency (QEext) and luminous efficiency (LE) of 4.1% and 6.1 cd/A, respectively, at current density ... |
