Abstract
An organometallic complex which includes a carboxylic acid as an ancillary ligand, and an organic electroluminescent device employing the same. The organometallic complex is useful as a phosphorescence dopant material of an organic electroluminescent device due to its high luminosity in the range of the blue wavelengths.
