Abstract: A compound is represented by a formula (1) below. In the formula (1): Ra and Rb not forming a ring are a substituent or the like; a combination of R5 and R6, combination of R6 and R7, or combination of R7 and R8 form a ring represented by a formula (10). In this case, positions a1 and b1, positions a2 and b1, or positions a3 and b1 are fused with each other. One or more of R1 to R4, R5 to R8 not forming a ring, and R9 to R12 are a substituent Rx. One or more of R4 to R6, R8, R9 and R12 not being Rx are a substituent Ry, and R1 to R12 other than Rx and Ry are a hydrogen atom or substituent. At least one hetero atom of when the substituent is a heterocyclic group only includes one or more of oxygen, sulfur and silicon.

Abstract: An organic electroluminescence device includes an anode, a cathode, and an emitting layer, in which the emitting layer contains a first compound represented by a formula (1) and a delayed fluorescent second compound represented by a formula (2), and singlet energy S1(M1) of the first compound and singlet energy S1(M2) of the second compound satisfy a relationship of Numerical Formula 1, S1(M2)>S1(M1) (Numerical Formula 1). In the formula, rings A, B, D, E, and F are each independently a cyclic structure selected from the group consisting of a substituted or unsubstituted aryl ring having 6 to 30 ring carbon atoms and a 10 substituted or unsubstituted heterocyclic ring having 5 to 30 ring atoms; one or both of the rings B and D are present; and one or both of the rings E and F are present
