Paragraph 0078; 0079; 0082, (2018/10/19)
The invention provides an aromatic amine derivative and an organic light-emitting device thereof, and relates to the technical field of organic photoelectric materials. The preparation method of the compound is simple, raw materials are easy to obtain, the high hole mobility and Tg and the good stability and film-forming property are achieved, the derivative has the proper highest occupied molecular orbital, and can be adopted as a first hole transmission layer and can also be adopted as a second hole transmission layer. When the derivative is adopted as the first hole transmission layer, theenergy level difference between a light-emitting layer and an anode interface can be lowered; when the derivative is adopted as the second hole transmission layer, the energy level difference betweenthe light-emitting layer and the first hole transmission layer can be lowered, and meanwhile point sum balance inside the light-emitting layer can be achieved. The derivative is applied to an OLED, the light-emitting efficiency and the color purity of the device can be remarkably improved, the service life of the device can be prolonged, the driving voltage of the device can be lowered, and the OLED material is good in performance.
