Objects of the invention are to provide an
organic compound having excellent properties, which is excellent in
electron-injecting / transporting performance, has hole-blocking ability, and is highly stable in a thin-film state, as a material for an organic electroluminescent devices having a high-efficiency and a high durability; and to provide an organic electroluminescent device having a high-efficiency and a high durability using the compound. The invention relates to: a compound having a pyridoindole ring structure bonded with a substituted pyridyl group, which is represented by the following general formula (1); and an organic electroluminescent device comprising a pair of electrodes and at least one
organic layer interposed between the electrodes, wherein the at least one
organic layer contains the compound.in which Ar represents a substituted or unsubstituted
aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group; R1 to R3 may be the same or different and represent a
hydrogen atom, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group; R4 to R11 may be the same or different and represent a
hydrogen atom, a
fluorine atom, a
chlorine atom, a cyano group, a
trifluoromethyl group, a linear or branched
alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted
aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group; m and n represent an integer of 1 to 3; and W, X, Y, and Z represent a
carbon atom or a
nitrogen atom, provided that the case where R1 to R3 in the molecule are simultaneously all
hydrogen atoms is excluded, and that only one of W, X, Y, and Z is a
nitrogen atom and the
nitrogen atom does not have the
substituent of R8, R9, R10, or R11.
