Compound having substituted bipyridyl group and pyridoinodole ring structure, and organic electroluminescent device

An organic electroluminescent device that comprises a pair of electrodes, and one or more organic layers sandwiched between the pair of electrodes, wherein a compound of the following general formula (1) in which a substituted bipyridyl group and a pyridoindole ring structure are bonded via a phenylene group, is used as a constituent material of at least one organic layer,

• wherein Ar1 represents a naphthyl group;
• Ar2 represents biphenyl, naphthyl-phenyl, phenyl-naphthyl, pyridyl-phenyl, pyridyl-naphthyl, bipyridyl, CF3-subsituted phenyl, F-substituted phenyl or an unsubstituted condensed polycyclic aromatic group;
• and R1 to R15 and R17 may be the same or different, and represent a hydrogen atom, a deuterium atom, a fluorine atom, a chlorine atom, a cyano group, a trifluoromethyl group, or a linear or branched alkyl group of 1 to 6 carbon atoms.
