Abstract

The invention relates to an aromatic amine derivative and an organic electronic device. The structure of the aromatic amine derivative is as shown in the general formula (1), and the definition of thesymbol in the general formula (1) is the same as in the description. The light emission wavelength of above-mentioned aromatic amine derivative has fluorescence emission at a short wavelength and, the light-emitting spectrum of which exhibits a narrow half-peak width, so that the substance has a deep blue fluorescence emission and has a high light-emitting efficiency. The organic electroluminescent element prepared with such an aromatic amine derivative has a deep blue color coordinate, a high luminous efficiency, and a long device life.

Description

technical field [0001] The invention relates to the technical field of electroluminescence, in particular to an aromatic amine derivative and an organic electronic device. Background technique [0002] Organic light-emitting diodes (Organic Light-Emitting Diode, OLED) have great potential in the application of optoelectronic devices (such as flat panel displays and lighting) due to the diversity of organic semiconductor materials, relatively low manufacturing costs, and excellent optical and electrical properties. Great potential. [0003] The organic electroluminescence phenomenon refers to the phenomenon of converting electrical energy into light energy by using organic substances. An organic electroluminescence element utilizing the organic electroluminescence phenomenon generally has a positive electrode, a negative electrode, and a structure including an organic substance layer therebetween. In order to improve the efficiency and lifespan of the organic electrolumines...
