First claim

Opening claim text (preview).

The invention claimed is: 1. A method for producing a cyclometalated iridium complex, the method comprising: 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): (in General Formula (1), Ir represents an iridium atom, and O represents an oxygen atom), wherein the aromatic heterocyclic bidentate ligand is represented by General Formula (5), and the cyclometalated iridium complex is represented by General Formula (6): (in General Formula (5), N represents a nitrogen atom, C represents a carbon atom, H represents a hydrogen atom, CyA is any one of a pyridine ring, a quinoline ring, an isoquinoline ring, an imidazole ring, and a triazole ring, CyB is a benzene ring, and CyA and CyB are optionally linked together to form a ring structure); and (In General Formula (6), Ir represents an iridium atom, N represents a nitrogen atom, C represents a carbon atom, H represents a hydrogen atom, CyA is any one of a pyridine ring, a quinoline ring, an isoquinoline ring, an imidazole ring, and a triazole ring, and is linked to iridium via the nitrogen atom of the ring, and CyB is a benzene ring, and is linked to iridium via the carbon atom ring; and CyA and CyB may be linked together to further form a ring structure). 2. The method for producing a cyclometalated iridium complex according to claim 1 , comprising using as a raw material an organoiridium compound represented by the following General Formula (2): (in General Formula (2), Ir represents an iridium atom, and O represents an oxygen atom; L represents a monodentate or bidentate ligand; Y represents a counter cation; Z represents 0 to 3; m represents 1 to 3; and n represents 0 to 4). 3. The method for producing a cyclometalated iridium complex according to claim 1 , comprising using as a raw material an organoiridium compound represented by the following General Formula (3): (in General Formula (3), Ir represents an iridium atom, and O represents an oxygen atom; X represents a monodentate ligand; Y represents a counter cation; Q represents 2 or 3). 4. The method for producing a cyclometalated iridium complex according to claim 1 , comprising using as a raw material an organoiridium compound represented by the following General Formula (4): (in General Formula (4), Ir represents an iridium atom, and O represents an oxygen atom; Y represents a counter cation; R represents 2 or 3).
