NITROGEN-CONTAINING HETEROCYCLIC DERIVATIVE AND ORGANIC ELECTROLUMINESCENT (EL) ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a new nitrogen-containing heterocyclic derivative useful as a constituent component of an organic EL element; and to achieve the organic EL element having high light emission intensity and light emission efficiency while being driven at a low voltage by using the nitrogen-containing heterocyclic derivative as at least one layer of organic compound layers. SOLUTION: The new nitrogen-containing heterocyclic derivative has a specific structure. At least one layer of the organic thin layers contains the nitrogen-containing heterocyclic derivative singly or as a component of a mixture in the organic electroluminescent element wherein the organic thin film layers composed of one or several layers including at least a light-emitting layer are interposed between a cathode and an anode.
