摘要

Disclosed is a compound represented by formula (1) which is useful as a material for organic electroluminescent elements. (In formula (1), Ar1 is an m-valent fused ring group of four or more fused rings including one or more rings selected from furan rings and pyran rings, HAr is any of the nitrogenous heterocyclic groups represented by formulae (2)-(5), L is a single bond, etc., and n and m are integers 1-5.) (In formulae (2)-(5), R11, R12, R21, R22, R31-R46 are hydrogen atoms, etc., X is N or CR13, R13 is a hydrogen atom, etc., Y is N or CR23, R23 is a hydrogen atom, etc., and Z is a bridging group such as a substituted or unsubstituted alkylene group.)
