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.
提供的是一种具有部分氟代取代基的辅助配体的有机发光材料。这种有机发光材料是一种具有部分氟代取代基的二酮辅助配体的金属配合物,可用作有机电致发光装置中的发光材料。这些新型金属配合物可以更有效地微调发射波长,降低电压,提高效率,延长寿命,并提供更好的器件性能。此外,还提供了一种有机电致发光装置和化合物配方。
