METAL COMPLEX AND LIGHT EMITTING ELEMENT PREPARED USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a metal complex useful for the production of a light emitting element having excellent external quantum yields.SOLUTION: The metal complex is represented by the formula (1), where nrepresents 1, 2 or 3, A-G-Arepresents an anionic bidentate ligand, R-Rrepresent an aryl group or the like, and a ring A represents an aromatic heterocycle.
