摘要：
Organic electroluminescence devices having the life of light emission superior to those of conventional electroluminescence devices, and novel arylenediamine derivatives which can remarkably improve the life of light emission of an organic electroluminescence device when the derivatives are used as a component of the device, are disclosed. The organic electroluminescence devices of the present invention at least contain a p-phenylenediamine derivative having 6 or more benzene ring skeletons, or at least a 4,4'-biphenylenediamine derivative having 5 biphenyl groups. The arylenediamine derivatives of the present invention include p-phenylenediamine derivatives having 4 biphenyl groups and 4,4'-biphenylenediamine derivatives having 5 biphenyl groups.
