A nitrogen-containing heterocyclic compound represented by the following formula (I):
1
wherein X
1
and X
2
each represent an electron attractive group such as a cyano group; and the rings Z
1
and Z
2
each represent a hydrocarbon ring or a heterocycle (e.g., benzene ring having an electron donative group such as hydroxyl group, an alkoxy group, amino group and an N-substituted amino group, or a condensed ring being a benzene ring condensed with a heterocycle having a nitrogen atom as a hetero atom) is provided. An organic EL device is obtained by allowing an organic layer containing the compound described-above to be interposed between a pair of electrodes. The present invention provides a nitrogen-containing heterocyclic compound useful as a functional material and a process for producing the same, and an organic EL device using the same.
