Organic electroluminescent device using the same and nitrogen-containing heterocyclic derivative having an electron-withdrawing substituents

摘要

Nitrogen-containing heterocyclic derivative novel with electron withdrawing substituents, and an organic electroluminescent device wherein an organic thin film layer composed of one or more layers including a light emitting layer is interposed at least between a cathode and an anode, the organic thin film layer By at least one layer of is, containing as a component of a mixture alone or the nitrogen-containing heterocyclic derivative, luminous efficiency to realize the organic EL element and a long life high.
