Abstract
Official abstract text for this publication.
The present disclosure relates to an aromatic amine derivative represented by general formula (I).The aromatic amine derivative has fluorescence emission at a short light emission wavelength, and the light-emission spectrum of the aromatic amine derivative has a narrow half-peak width, and accordingly, the material has deep-blue fluorescence emission and has a very-high light emission efficiency. An organic electroluminescent component prepared by using the aromatic amine derivative has deep-blue color coordinates, a high light emission efficiency and a long life-span.
