Abstract
Provided is a light-emitting material having a polycyclic ligand. The light-emitting material is a novel metal complex comprising a polycyclic ligand having a structure of Formula 1 and may be used as light-emitting material in an electroluminescent device. These novel metal complexes can greatly red-shift the maximum emission wavelengths of electroluminescent devices and significantly adjust emitting colors of the devices and have very narrow emission spectra and can greatly improve the luminescence saturation of the devices and provide better device performance. Further provided are an electroluminescent device and a compound combination.
