Document Type and Number:
WIPO Patent Application WO/2020/136496
Kind Code:
A1
Abstract:
Provided is an organic metal complex having a light emission peak in a long wavelength region (visible region or near-infrared region of at least 700 nm). The present invention provides an organic metal complex represented by general formula (G1), in which a ligand having a quinoxaline skeleton is coordinated to a central metal, and which has an electron attractive group (e.g., a fluorine atom, a cyano group, a trifluoromethyl group, a trifluoromethylsulfonyl group, a pentafluorosulfanyl group, or the like) as a substituent in at least one substitutable position of a benzene ring condensed with the quinoxaline skeleton of the ligand.
