摘要：
A light-emitting material comprises iridium and at least one ligand represented by the following formula: wherein R11 and R12 each represents an alkyl group, an aryl group, a heteroaryl group, an alkoxy group, a cyano group or a cyclic structure obtained by connection of one of a plurality of R11s to another of said plurality of R11s, or one of a plurality of R12s to another of said plurality of R12s, or one of the R11s to one of the R12s; m1 represents an integer from 0 to 4; m2 represents an integer from 0 to 6.
