Abstract
Provided is a luminescent material having a polycyclic ligand. The luminescent material is a new metal complex having a polycyclic ligand and may be used as luminescent materials in electroluminescent devices. These new metal complexes achieve red light emission, have a very narrow full width at half maximum, and can achieve high saturation luminescence. In addition, these new metal complexes, when used as luminescent materials in electroluminescent devices, can achieve red light emission, have a very narrow full width at half maximum, achieve high saturation luminescence, reduce or maintain a low voltage, greatly improve device efficiency and lifetime, and provide better device performance. Further provided are an electroluminescent device and a compound composition.
