Abstract

Provided are an organic electroluminescent material and a device thereof. The organic electroluminescent material is a metal complex including a ligand Lhaving a structure of Formula 1, and the metal complex can be used as luminescent materials in electroluminescent devices. These new compounds, when used in electroluminescent devices, can show better performance, provide lower device voltage and higher device efficiency, and significantly improve the comprehensive performance of devices. Further provided are an electroluminescent device including the metal complex and a compound composition including the metal complex.
