Provided are a phosphorescent organometallic complex and a use thereof. The metal complex has a ligand with a structure represented by Formula 1 and may be used as a light-emitting material in an electroluminescent device. These novel metal complexes can not only maintain low voltage and improve device efficiency in electroluminescent devices but also greatly reduce the half-peak width of light emitted by these devices so as to greatly improve color saturation of the light emitted by these devices, thereby providing better device performance. Further provided are an electroluminescent device and a compound formulation.
