Abstract:
A compound is represented by a formula (1). In the formula (1); Ar represents an aromatic hydrocarbon group or a heterocyclic group having 4 or more fused rings and 22 or less ring atoms; Ar optionally has a substituent; R11 is a substituted or unsubstituted aromatic hydrocarbon group; when R11 is an aromatic hydrocarbon group having a substituent, the substituent is not a heterocyclic group; X1 represents a nitrogen atom or a carbon atom bonded with R12 (CR12); R12 represents a hydrogen atom or a substituent; L1 represents a single bond or a linking group; X2 and X3 each independently represent a nitrogen atom or a carbon atom bonded with R2 (CR2); R1 and R2 each independently represent a hydrogen atom or a substituent; and L2 is a linking group.
