Document Type and Number:
Japanese Patent JP7275042
Kind Code:
B2
Abstract:
The present invention provides a novel organometallic complex. The present invention also provides a novel organometallic complex having superior heat resistance. The present invention additionally provides a novel organometallic complex having excellent color purity. Specifically provided is an organometallic complex represented by general formula (G1) and characterized in that: a pyrimidine ring coordinated to Ir has at least one phenyl group having a cyano group as a substituent; and the phenyl group having the cyano group is bound to position 6 of the pyrimidine ring. (In the formula, R1 to R4 each independently represent hydrogen, a C1–6 alkyl group, a substituted or unsubstituted cycloalkyl group having five to seven ring-forming carbon atoms, a substituted or unsubstituted aryl group having six to 13 ring-forming carbon atoms, or a substituted or unsubstituted heteroaryl group having three to 12 ring-forming carbon atoms. R5 to R9 each independently represent hydrogen, a C1-6 alkyl group, a substituted or unsubstituted aryl group having six to 13 ring-forming carbon atoms, a substituted or unsubstituted heteroaryl group having three to 12 ring-forming carbon atoms, or a cyano group, with at least one of the radicals representing a cyano group. L represents a monoanionic ligand. n represents an integer from 1 to 3.)
