Abstract
The present invention provides a method for producing a cyclometalated iridium complex, the method including producing a cyclometalated iridium complex by reacting a cyclometalated iridium complex raw material including an organoiridium material with an aromatic heterocyclic bidentate ligand capable of forming an iridium-carbon bond and an iridium-nitrogen bond, and using as the raw material an organoiridium material represented by the following general formula (1). The present invention allows a cyclometalated iridium complex to be produced with a high yield without by-production of a halogen-crosslinked iridium dimer.
