Organic light emitting diode containing a Ir complex having a novel ligand as a phosphorescent emitter

摘要

An organic light emitting diode with Ir complex is disclosed in this specification, wherein the Ir complex is used as the phosphorous emitter. The chemical containing pyridyl triazole or pyridyl imidazole functional group is used as the auxiliary monoanionic bidentate ligand in the mentioned Ir complex, so that the CIE coordinate of the mentioned Ir complex is adjustable and the light emitting performance of the Ir complex is improved.
