Abstract:
An organometallic compound includes a hexadentate ligand bonded to a metal atom (M1). An energy level (E3MC) of a 3MC state (triplet metal centered state) of the organometallic compound is higher than an energy level (E3MLCT) of a 3MLCT state (triplet metal-to-ligand charge transfer state) of the organometallic compound.
