Cyclic azine derivatives and methods for their manufacture, and to their use as a constituent organic electroluminescent device has

In the general formula (1) cyclic azine derivative represented by the formula (1), Ar 1 represents an optionally substituted C1-4 alkyl, phenyl or pyridyl aromatic group. A represents the general formula (2) to (5) a group represented described in the specification. The cyclic azine derivatives as fluorescent and phosphorescent organic electroluminescent organic compound layer is a light emitting device is useful.
