摘要:
A cyclic azine compound represented by general formula (1): wherein each Ar1 represents an aromatic group, which is unsubstituted or substituted by a C1-4 alkyl 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.
摘要:
A 1,3,5-triazine derivative represented by formula (1): wherein R1 is hydrogen, C1-4 alkyl 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.
