Abstract: A compound represented by a formula (1). In the formula (1): a ring A1, a ring B1, a ring C1, and a ring D1 are each independently a substituted or unsubstituted ring; Za, Zb, Zc, and Zd are each independently a nitrogen atom or a carbon atom; the ring C1 and the ring D1 are mutually bonded to form a ring or not mutually bonded; R1 is a hydrogen atom, substituent, or the like; R1 is mutually bonded to the ring A1 to form a ring or not mutually bonded; R1 is mutually bonded to the ring B1 to form a ring or not mutually bonded; and at least one of R1, the ring A1, the ring B1, the ring C1, or the ring D1 has a group represented by —N(R1A)(R2A).
