摘要： The present invention relates to a raw material for a cyclometalated iridium complex, and provides a technique that makes it possible to obtain a cyclometalated iridium complex in higher yield at a lower reaction temperature than using tris(2,4-pentanedionato)iridium(III). The present invention relates to a raw material for a cyclometalated iridium complex, including an organic iridium material for producing a cyclometalated iridium complex, the organic iridium material being a tris(β-diketonato)iridium(III), in which an asymmetric β-diketone is coordinated to iridium.

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 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.

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.
