<p>Disclosed is a novel nitrogen-containing heterocyclic derivative having a specific structure. Also disclosed is an organic electroluminescent device wherein an organic thin film composed of one or more layers including at least a light-emitting layer is interposed between a cathode and an anode, and at least one layer of the organic thin film contains the nitrogen-containing heterocyclic derivative by itself or as a component of a mixture. Consequently, the organic electroluminescent device is able to have high emission luminance and high luminous efficiency, while being operated at a low voltage. ® KIPO & WIPO 2009</p> |
