A series of copper(I)-diimine complexes, [Cu(bdpp)(bpy)]BF4 (1), [Cu(bdpp) (pen)]BF4 (2), [Cu(bdpp)(damp)]BF4 (3), [Cu(bdpp)(pen)]BF4 (4) (bdpp = 4,6-bis-(biphenylphosphino)phenoxazine, bpy = 2,2′-bipyridine, phen = 1,10-Phenanthroline, dmp = 2,9-dimethyl-1,10-phenanthroline, bphen = 4,7-diphenyl-1,10-phenanthroline), were synthesized and characterized by IR, 1H NMR, 31P NMR, XRD and x-ray crystal structure anal. Structural anal. reveals that each Cu+ in 1-4 is four-coordinated by two N atoms and two P atoms and adopts a distorted tetrahedral geometry. DFT calculations show that the HOMOs in 1-4 are mainly comprised of bdpp and copper d-orbitals, while the LUMOs are mainly dominated by diimine ligands. Calculation of at. charges indicates that the charges of the central Cu atoms in 1-4 are less than + 1, and the diimine ligands may be the key to the metal charge transfer to the coordinated atom. In 1-4, the maximum phosphorescent lifetimes and quantum yields are up to 349μs and 22%, resp. Moreover, complex 3 was used for fabricating the LED device, showing a decent performance with the maximum EQE of 11%.
