摘要:
An anthracene derivative is represented by the following formula (1). In the formula (1), one of R11 to R20 is used to bond to L1, and is a single bond. The remainder of R11 to R20 that are not used to bond to L1 are independently a hydrogen atom, a halogen atom, a cyano group, a substituted or unsubstituted alkyl group including 1 to 20 carbon atoms, or the like. L1 is a single bond, a substituted or unsubstituted divalent aromatic hydrocarbon group including 6 to 50 ring carbon atoms, or the like. Z has a structure represented by the following formula (2). In the formula (2), one of R1, R3, and R4 is used to bond to L1, and is a single bond. The remainder of R1, R3, and R4 that are not used to bond to L1, R2, and R5 to R10 are independently a hydrogen atom, a halogen atom, a cyano group, a substituted or unsubstituted alkyl group including 1 to 20 carbon atoms, or the like. At least one pair of groups among R5 to R8 that are adjacent to each other are bonded to each other to form a saturated or unsaturated hydrocarbon ring.
