Abstract:
A material for electroluminescent devices which comprises a compound in which a heterocyclic group having nitrogen is bonded to carbazolyl group and an organic electroluminescent device having at least one organic thin film layer which is sandwiched between the cathode and the anode and contains the above material in at least one layer, are provided. The material can provide organic electroluminescent devices emitting bluish light with a high purity of color. The organic electroluminescence device uses the material.
