Abstract
Provided are a phosphorescent organometallic complex and a device thereof. The organometallic complex contains a ligand La having a structure of Formula 1 and a ligand Lb having a structure of Formula 2. Such metal complexes can be used as light-emitting materials in electroluminescent devices. These novel compounds in organic electroluminescent devices can effectively improve efficiency, reduce device voltage, and provide better device performance. Further provided are an organic electroluminescent device containing the metal complex and a compound composition containing the metal complex.
