Abstract
Provided is an organic light-emitting material having an ancillary ligand with partially fluorinated substituents. The organic light-emitting material is a metal complex having a diketone ancillary ligand with partially fluorinated substituents and may be used as a light-emitting material in an organic electroluminescent device. These new types of metal complex can fine-tune the emission wavelength more effectively, reduce voltage, improve efficiency, prolong lifetimes, and provide better device performance. Further provided are an organic electroluminescent device and a compound formulation.
