Kind Code:
A1
Abstract:
ABSTRACT Provided is a novel organic metal complex. Also provided in one embodiment of the present invention is a novel organic metal complex having a high quantum yield. The organic metal complex is an Ir complex having a structure represented by general formula (G-1) that includes a 1H-naphtho[1,2-d]imidazole skeleton as a ligand. Among the N in the 1H-naphtho[1,2-d]imidazole skeleton, the N that is not bonded to Ir is bonded to a substituted or unsubstituted aryl group. In general formula (G-1), R1 to R10 each independently represent a hydrogen, a C1-6 alkyl group, a substituted for unsubstituted C3-7 cycloalkyl group, a substituted or unsubstituted C6-25 aryl group, or an electron withdrawing group, and Ar represents a substituted or unsubstituted C6-25 aryl group.
