To provide a copper complex which emits light with high efficiency, and an organic light-emitting device using the same.
A copper complex represented by general formula (1) is provided [in formula (1), each of R1s is independently selected from halogen atoms of chlorine, bromine, and iodine, and phenyl acetylide, and benzenethiolato, each of phenyl acetylide and benzenethiolato optionally has a 1-4C alkyl group as a substituent; each of R2s is independently selected from a hydrogen atom, a 1-6C alkyl group or a phenyl group, the alkyl group optionally has a halogen atom as a substituent, the phenyl group optionally has a 1-4C alkyl group as a substituent; each of R3s is independently selected from a 1-6C alkyl group or a phenyl group, the phenyl group optionally has a 1-6C alkyl group or a halogen atom as a substituent; and Cu represents a monovalent copper ion].
