Abstract:
A metal complex containing three different ligands which may be used as a light-emitting material in a light-emitting layer of an organic electroluminescent device. These new complexes can not only achieve device performed desired to be adjusted or improved by adjusting substituents but also have the effect of effectively controlling increase of the evaporation temperature. Further disclosed are an electroluminescent device and a compound formulation including the metal complex.
