摘要
A novel nitrogen-containing heterocyclic compound having an electron-attracting substituent and an organic electroluminescence device comprising an anode, a cathode and an organic thin film layer which comprises a single layer or a plurality of layers comprising at least a light emitting layer and is disposed between the anode and the cathode, wherein at least one layer in the organic thin film layer comprises the above nitrogen-containing heterocyclic derivative singly or as a component of a mixture. The organic electroluminescence device exhibits a great efficiency of light emission and has a long life.
