tris‐heteroleptic phosphorescent cyclometalated IrIII complexes with two different cyclometalating ligands and one ancillary ligand was synthesized. Through manipulation of the electronic features of individual cyclometalating ligands, not only the emission color and electrochemical properties of these IrIII complexes can be tuned, but also unique charge carrier injection and transport traits can be conferred
合成了一系列具有两种不同的环金属化配体和一个辅助配体的三杂多磷光环金属化的Ir III配合物。通过操纵各个环金属化配体的电子特征,不仅可以调节这些Ir III配合物的发射颜色和电化学性质,而且可以赋予它们独特的电荷载流子注入和传输特性。由于与这些三杂多感官结构相关的增强的电子注入/传输和双极性特性,这些Ir III发射体显示出非常令人印象深刻的电致发光性能,最大外部量子效率为20.20%,发光效率为69.41 cd A -1,功率效率为35.15 Lm W -1。这些结果为设计和合成用于磷光有机发光二极管的高效电致磷光体提供了新的出路。
