A cyclic azine compound represented by general formula (1): wherein each Arrepresents an aromatic group, which is unsubstituted or substituted by a Calkyl group, a phenyl group or a pyridyl group; and A represents a group selected from those which are represented by general formulae (2) to (5), described in the description. The cyclic azine compound is useful for an organic compound layer of fluorescent or phosphorescent EL device.

A 1,3,5-triazine derivative represented by formula (1): wherein Ris hydrogen, Calkyl group or substituted or unsubstituted phenyl group; n is an integer of 1-3, Ar is a substituted or unsubstituted aromatic hydrocarbon group, provided that Ar is different from two substituted quarterarylenyl groups bonded to the 1,3,5-triazine ring; and V and Y are nitrogen or carbon, provided that a case where both of V and Y are carbon atoms is excluded. The organic electroluminescent device comprising the 1,3,5-triazine derivative as an electron transport material has a long lifetime.
