AROMATIC AMINE DER1VATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

An object of the present invention has a high luminous efficiency even after high temperature storage, and provides an aromatic amine derivative which has a long lifetime organic EL device, and realize it. The aromatic amine derivative, is represented by the general formula (1). In the equation (1) of, Ar ₁ is to be represented by the general formula _(2), Ar 2 is represented by the following formula (3);
