The structureâproperty correlations of a set of heteroleptic red- and green-emitting Ir(III) complexes with different temperature sensitivities and charge trapping capabilities are described, revealing superb performance in multi-layer phosphorescent organic light-emitting diodes (PhOLEDs) expressed by very high maximum luminous efficiencies up to 36.8 cd Aâ1. Using 2-phenylpyridine and with 2-(naphthalen-1-yl)pyridine as the CâN ligand, the resulting red emitting complex featured a maximum luminous efficiency of 10.8 cd Aâ1; one of the most excellent device performances within this class of red Ir(III) emitters.
该研究描述了一组具有不同温度敏感性和电荷捕获能力的异极红绿发光铱(III)配合物的结构与性能相关性,揭示了其在多层磷光有机发光二极管(PhOLED)中的卓越性能,其最大光效高达 36.8 cd Aâ1。使用 2-苯基吡啶和 2-(萘-1-基)吡啶作为 CâN 配体,得到的红色发光复合物的最大发光效率为 10.8 cd Aâ1 ;这是该类红色 Ir(III) 发光体中性能最出色的器件之一。
