New Indium Complexes with Cyclometalated Alkenylquinoline Ligands as Highly Efficient Saturated Red-Light Emitters for Organic Light-Emitting Diodes

摘要

We have demonstrated for the first time the synthesis of iridium complexes based on a alkenylquinoline and -isoquinoline framework. The devices based on these iridium complexes emit highly saturated red light with the external quantum efficiency, brightness, and CIE coordinates among the best reported so far. We are now working on the synthesis of platinum and other metal complexes based on these ligand frameworks and their application in OLEDs.
