Zusammenfassung: | To provide a novel polycyclic compound capable of improving the luminous efficiency and element lifetime of a light-emitting element and to provide a light-emitting element including the polycyclic compound.SOLUTION: There is provided a 2-arylquinoline-based polycyclic compound represented by the following chemical formula 1. (In the formula, R1 and R2 are independently a hydrogen atom, a deuterium atom, a halogen atom, a silyl group, an amino group, an alkyl group, an alkenyl group, an aryl group having a ring-forming carbon number of 6 or more and 30 or less, a heteroaryl group having a ring-forming carbon number of 2 or more and 30 or less, or are bonded to an adjacent group to form a ring, n is an integer of 0 to 4 and m is an integer of 0 to 6.)SELECTED DRAWING: Figure 3
