a substituted or unsubstituted heterocyclic ring including 5 to 50 ring atoms;
R1 and R2 independently form a substituted or unsubstituted heterocyclic ring by bonding with the ring a, the ring b, or the ring c, or do not form a substituted or unsubstituted heterocyclic ring; and
R1 and R2 which do not form the substituted or unsubstituted heterocyclic ring are independently
a substituted or unsubstituted alkyl group including 1 to 50 carbon atoms,
a substituted or unsubstituted alkenyl group including 2 to 50 carbon atoms,
a substituted or unsubstituted alkynyl group including 2 to 50 carbon atoms,
a substituted or unsubstituted cycloalkyl group including 3 to 50 ring carbon atoms,
a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms, or
a substituted or unsubstituted monovalent heterocyclic group including 5 to 50 ring atoms.
Each of the ring a, the ring b, and the ring c is a ring which is fused with a central fused bicyclic structure of the formula (1) composed of B atom, two N atoms, and carbon atom, and a substituted or unsubstituted aromatic hydrocarbon ring including 6 to 50 ring carbon atoms, or a substituted or unsubstituted heterocyclic ring including 5 to 50 ring atoms.
