ABSTRACT:
Provided are a nitrogen-containing heterocyclic derivative having a specific structure and an organic electroluminescence device in which an organic thin film layer comprising a single layer or plural layers including at least a light emitting layer is interposed between a cathode and an anode, wherein at least one layer in the above organic thin film layer contains the nitrogen-containing heterocyclic derivative described above in the form of a single component or a mixed component, and thus provided are the organic electroluminescence device which emits blue light having a high light emitting luminance and a high current efficiency and the novel nitrogen-containing heterocyclic derivative which materializes the same.
