Organic luminescent materials containing cycloalkyl ancillary ligands is 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 cycloalkyl containing acetylacetone type ancillary ligands. These novel ligands can effectively improve the lifetime of the device, change the sublimation characteristics and improve device performance. Also disclosed are an electroluminescent device and a formulation.
