Abstract
A metal complex with fluorine substitution is disclosed, which employs a series of new ligands containing fluorine-substituted structure can be used as a luminescent material in an emissive layer of an electroluminescent device. By using the metal complex can provide much longer device lifetime, better thermal stability, no blue-shifted illumination, and higher luminous efficiency. An electroluminescent device and compound formulation are also disclosed.
