The new azomethine metal complexes were synthesized and three complexes among them were applied to the organic electroluminescent devices as a blue or white light-emitting layer. Emission wavelengths were observed at the region of 420-540 nm in luminescence spectra for these complexes. Their HOMO, LUMO and band gaps were investigated with cyclic voltammetry and found to be consistent with their UV-vis absoption spectral data.
