摘要： 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 compound 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 compound including a substructure represented by the following General Formula (1). The present invention is capable of producing a cyclometalated iridium complex with a high yield without by-production of a halogen-crosslinked iridium dimer. (in General Formula (1), Ir represents an iridium atom, and O represents an oxygen atom).

摘要： The present invention provides a method for producing a cyclometalated iridium complex by use of a non-chlorine iridium raw material. The method for producing a cyclometalated iridium complex includes producing a cyclometalated iridium complex by reacting a raw material including an iridium compound with an aromatic heterocyclic bidentate ligand capable of forming an iridium-carbon bond, the raw material being non-halogenated iridium having a conjugated base of a strong acid as a ligand. Here, the non-halogenated iridium is preferably one containing a conjugated base of a strong acid having a pKa of 3 or less as a ligand.
