Material for organic electroluminescent devices and organic electroluminescent devices made by using the same

摘要

A phosphorescence device comprising an anode, a cathode and an organic thin film layer comprising at least one layer which is disposed between the anode and the cathode. The at least one layer in the organic thin film layer comprises a material comprising a compound in which a heterocyclic group having nitrogen is bonded to an arylcarbazolyl group or a carbazolylalkylene group. The material can provide a phosphorescence device emitting bluish light with a high purity of color.
