AROMATIC AMINE DERIVATIVE, ORGANIC ELECTROLUMINESCENT ELEMENT EMPLOYING THE SAME, AND PROCESS FOR PRODUCING AROMATIC AMINE DERIVATIVE

摘要

An aromatic amine derivative having a specific structure comprising a substituted pyrene structure and a substituted diphenylamino group bonded thereto; an organic electroluminescent element comprising a cathode, an anode, and an organic thin film layer sandwiched therebetween which is composed of one or more layers comprising a luminescent layer, wherein at least one layer of the organic thin film layer consists of the aromatic amine derivative alone or contains the derivative as a component of a mixture; and a process for producing the aromatic amine derivative. The organic electroluminescent element has a long life and a high luminescent efficiency and emits a blue color. The aromatic amine derivative realizes the element.
