Abstract:
A material for organic EL device which includes a compound having a specific structure: an azine ring having a cyano-substituted aromatic hydrocarbon group, an azine ring having a cyano-substituted heterocyclic group, or an azine ring having a cyano group directly bonded to the azine ring. An organic electroluminescence device including an organic thin film layer between a cathode and an anode, wherein the organic thin film layer includes a light emitting layer and at least one layer containing the material for organic electroluminescence device, has a long lifetime.
