ORGANIC METAL COMPLEX, LIGHT-EMITTING DEVICE, LIGHT-EMITTING APPARATUS, ELECTRONIC EQUIPMENT, AND ILLUMINATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/156886
Kind Code:
A1
Abstract:
Provided is a new organic metal complex that improves the light emission efficiency of a light-emitting device. The present invention provides an organic metal complex represented by general formula (G1). In the formula, X represents carbon or nitrogen, and the carbon is bonded to hydrogen (including deuterium), a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, or a substituted or unsubstituted aryl group. In addition, R1-R3 each independently represent hydrogen (including deuterium), a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, or a substituted or unsubstituted aryl group. Further, n represents an integer of 1-4. The respective borate ligands may be the same or different from each other. Each n may be the same or different from the others. When n is equal to or more than 2, X, R1, and R2 may each be the same or different from the others. When n is equal to or less than 2, each R3 may be the same or different from the others.
