摘要： A new class of organometallic complexes having the following general formula:

where:

M 2 is a divalent metal; and
R 1 to R 8 represent substitution possibilities at each position and each represents hydrogen or hydrocarbon groups or functional groups,
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.
