制备了嵌入宽间隙聚（9,9′-烷基- 3,6 -硅氟芴）（PSiFC6C6）的含铱（III）双（2,4-二氟苯-2-吡啶）（2-（4h - 1,2,4 -三唑-3-基）吡啶）[Ir(PPF)2(PZ)]配合物的高效蓝色聚合物磷光有机发光二极管（PPHOLED）。尽管PSiFC6C6主体聚合物显著猝灭了铱配合物的光磷光发射，但掺杂Ir(PPF)2（PZ）的有机发光二极管在聚合物主体PSiFC6C6中发射出高效率的蓝光，峰值波长为462nm。在644cd / m2时，最大的外量子效率和发光效率分别为4.8%光子/电子和7.2cd∕A，国际发光委员会坐标为（0.15,0.26）。
Highly efficient blue polymer phosphorescent organic light-emitting diode (PPHOLED)-containing iridium(III) bis (2,4-difluorophenyl-2-pyridine) (2-(4H-1, 2, 4-triazol-3-yl)pyridine) [Ir(PPF)2(PZ)] complex embedded into wide-gap poly (9,9′-alkyl-3, 6-silafluorene) (PSiFC6C6) has been fabricated. Despite the significant quenching of photophosphorescence emission of the iridium complexes by a PSiFC6C6 host polymer, organic light-emitting diodes containing Ir(PPF)2(PZ) doped into the polymer host PSiFC6C6 emit high-efficiency blue light peaked at 462nm. The maximal external quantum and luminance efficiencies were, respectively, 4.8% photons/electrons and 7.2cd∕A at 644cd∕m2 and with Commission Internationale de l’Eclairage coordinates of (0.15,0.26).
