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.

Claim (Index 1):
A method for producing a cyclometalated iridium complex represented by the following General Formula (3), the method comprising producing a cyclometalated iridium complex by reacting a cyclometalated iridium complex raw material including an organoiridium material represented by the following General Formula (1) with an aromatic heterocyclic bidentate ligand capable of forming an iridium-carbon bond and represented by the following General Formula (2) and an iridium-nitrogen bond, wherein the aromatic heterocyclic bidentate ligand represented by the General Formula (2) is reacted with 1.5 times or more and less than 3 times the molar amount of the iridium compound represented by the General Formula (1); (In General Formula (1), Ir represents an iridium atom, and O represents an oxygen atom; L represents a ligand capable of forming an iridium-oxygen bond; R 1 , R 3 , R 4 , R 6 , R 7  and R 9  each independently represent an alkyl group; R 2 , R 5  and R 8  each independently represent a hydrogen atom or an alkyl group; and some or all of hydrogen atoms of the alkyl group may be substituted with halogen atoms). (in General Formula (2), N represents a nitrogen atom, C represents a carbon atom, H represents a hydrogen atom, CyA represents a five-membered or six-membered cyclic group containing nitrogen atoms, CyB represents a five-membered or six-membered cyclic group containing carbon atoms, and CyA and CyB may be linked together to form a ring structure), and (In General Formula (3), Ir represents an iridium atom, N represents a nitrogen atom, C represents a carbon atom, CyA represents a five-membered or six-membered cyclic group containing nitrogen atoms, and is linked to iridium via the nitrogen atoms, and CyB represents a five-membered or six-membered cyclic group containing carbon atoms, and is linked to iridium via the carbon atoms; CyA and CyB may be linked together to further form a ring structure; R 10  and R 12  each independently represent an alkyl group, R 11 s each independently represent a hydrogen atom or an alkyl group, and some or all of hydrogen atoms of the alkyl group may be substituted with halogen atoms; m is 2, and n is 1).
