Summary: | PURPOSE: A novel heterocyclic derivative containing nitrogen is provided to ensure high electronic stability, high luminescent degree, and long lifetime. CONSTITUTION: A heterocyclic derivative containing nitrogen is denoted by chemical formula 1. In chemical formula 1, R is halogen atom, or substituted or non-substituted aliphatic hydrocarbon group. An organic electroluminescence device containing electron transport layer(ETL) with the heterocyclic derivative. The organic electroluminescence device comprises anode(hole injection electrode), hole injection layer, hole transport layer, light emitting layer, electron transport layer, electron injection layer, and anode(electron injection electrode). |
