Abstract
Organic luminescent materials containing fluorine ancillary ligands are disclosed, which can be used as emitters in the emissive layer of an organic electroluminescent device. The organic luminescent materials is metal complexes which comprise a new series of fluorine containing acetylacetone type ancillary ligands. These novel ligands are effective in tuning the emission color, changing the sublimation properties, improving quantum efficiency and improving device performance. Also disclosed is an electroluminescent device and a formulation.
