Abstract
Provided is an organic light-emitting material. The light-emitting material is a series of metal complexes containing a ligand(s) based on isoquinoline which is substituted with deuterium at 3- and 4-position and a ligand(s) based on acetylacetone. The compounds can be used as the light-emitting material in an emissive layer of an organic electroluminescent device. These novel compounds can provide better device performance. Further provided are an electroluminescent device and a compound combination including the light-emitting material.
