METHOD OF PREPARING IRIDIUM COMPLEX AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE IRIDIUM COMPLEX PREPARED THEREBY

摘要

The present invention reacts an iridium intermediate with a ligand compound in the presence of a mixed solvent including a halogen-containing solvent and an alcohol-based solvent to produce an iridium complex having a heteroleptic fac-Ir(C^N) 2 (C^N)' structure with high selectivity. And a method for producing in a yield, and to an organic electroluminescent device using the iridium complex prepared by the method.
