Abstract:
A material for organic electroluminescence device having a specific central skeleton to which a cyano-substituted aromatic hydrocarbon group or a cyano-substituted heterocyclic group is bonded at its specific position is described. Further described is an organic electroluminescence device including an organic thin film layer between an anode and a cathode. The organic thin film layer include an light emitting layer and at least one layer of the organic thin film layer contains the material for organic electroluminescence device. The material for organic electroluminescence device realizes an organic electroluminescence device with good emission efficiency.
