ABSTRACT:
A new class of organometallic complexes for use in electroluminescent (EL) devices and a method of preparation are disclosed. The organometallic complexes are prepared by mixing organic ligands with metal salts in the presence of a base and a layer is formed in an EL device by vacuum evaporation. The organometallic material in the EL device serves as either an electron transporting layer or a light emission layer, or both.
