L1 and L2 are each independently a single bond or a bivalent group derived from an alkane, an arene, or a heteroarene having 1 to 20 carbon atoms,
Het1 and Het2 are each independently a dibenzopiperidine derivative substituent having less than or equal to 20 carbon atoms, and
R is a hydrogen atom, a deuterium atom, a fluorine atom, a chlorine atom, a cyano group, a trifluoromethyl group, a nitro group, a substitutable alkyl group having a straight or branched chain of 1 to 6 carbon atoms, a substitutable cycloalkyl group of 5 to 20 carbon atoms, a substitutable alkenyl group having a straight or branched chain of 2 to 6 carbon atoms, a substitutable alkyloxy group having a straight or branched chain of 1 to 6 carbon atoms, a substitutable cycloalkyloxy group, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, a substituted or unsubstituted condensed polycyclic aromatic group, or a substituted or unsubstituted aryloxy group having 5 to 20 carbon atoms, in which monovalent, divalent, or adjacent two substituents may have a cyclic structure, and n is an integer of 0 to 7.
