NITROGENOUS HETEROCYCLIC DERIVATIVE AND ORGANIC ELECTROLUMINESCENCE DEVICE MAKING USE OF THE SAME

摘要

A nitrogenous heterocyclic derivative of specified structure; and an organic electroluminescence device comprising a negative electrode and a positive electrode and, interposed therebetween, one or two or more organic thin-film layers having at least a light emitting layer, wherein at least one of the organic thin-film layers contains the above nitrogenous heterocyclic derivative alone or as a component of mixture. Thus, there is provided an organic electroluminescence device that while ensuring low voltage, exhibits high emission brightness and luminous efficiency, and provided a nitrogenous heterocyclic derivative for realization of such an organic electroluminescence device.
