PHOSPHORESCENT METAL COMPLEX COMPOUND, LIGHT EMITTING ELEMENT COMPRISING PHOSPHORESCENT METAL COMPLEX COMPOUND, AND METHOD FOR PRODUCTION OF PHOSPHORESCENT METAL COMPLEX COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a novel phosphorescent compound which can emit colored, e.g., deep blue, light blue, blue-green or green light and is stable; and a light emitting element comprising the phosphorescent compound.SOLUTION: A phosphorescent metal complex compound comprises at least one metallic central atom M and at least one ligand coordinated by the metallic central atom M. One of the metallic central atoms M and the ligand form a six-membered metallacyclic ring.
