摘要:
A cyclic azine compound represented by general formula (1):
wherein each Ar 1 represents an aromatic group, which is unsubstituted or substituted by a C 1-4 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.
wherein, Y is C-H or a nitrogen atom, Ar 1 is a C 6-18 aromatic hydrocarbon group, which may be substituted with an C 1-4 alkyl group or a phenyl group, Ar 2 is a hydrogen atom, or a C 6-18 aromatic hydrocarbon group, which may be substituted with a phenyl group or a pyridyl group, or is a nitrogen-containing condensed ring C 9-15 aromatic group, Ar 3 is a nitrogen-containing condensed ring C 9-15 aromatic group, X is a phenylene group, and n is an integer in the range of 0-3. The cyclic azine compound is useful as a constituent of an organic electroluminescent device.

摘要:
A 1,3,5-triazine derivative represented by formula (1):
wherein R 1 is hydrogen, C 1-4 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.

A 1, 3, 5-triazine derivative represented by the formula (1) :
wherein R 1 , R 2 and R 3 each independently represent a hydrogen atom or a methyl group; X represents a carbon atom or a nitrogen atom; Ar 1 represents a substituted or unsubstituted aromatic hydrocarbon group; Ar 2 represents an C 1-4 alkyl-substituted or unsubstituted aromatic 6-membered heterocyclic group having one or two nitrogen atoms, which may be a condensed ring compound. An organic electroluminescent device comprising the 1,3,5-triazine derivative exhibits low power consumption and long lifetime.
