In general formula (II), Rα1 to Rα8 and Rβ1 to Rβ8 each independently denote a hydrogen atom or a monovalent substituent, M denotes two hydrogen atoms, a metal, a metal oxide, or a metal having a ligand. A1═N—B1  General formula (III) A1 denotes a substituted or unsubstituted heterocyclic group, a substituted aliphatic group, or a substituted or unsubstituted carbocyclic group, and B1 denotes a substituted or unsubstituted heterocyclic group or a substituted or unsubstituted aryl group.
