Paragraph 0064-0066, (2018/03/01)
The invention provides an aromatic amine derivative and an organic light-emitting device using the same and relates to the technical field of organic optoelectronic materials. Carbazole structures have higher redox potential values and good stability under air or illumination conditions. Therefore, by introducing the carbazole structures, the obtained aromatic amine derivative disclosed by the invention shows good thermal stability, can be used for preparing the organic light-emitting device and particularly shows the advantages of high efficiency and low driving voltage when being used as a hole transmission material in the organic light-emitting device; the aromatic amine derivative is an organic light-emitting material with excellent performance; the organic light-emitting device disclosed by the invention is superior to an existing common OLED (Organic Light Emitting Diode) device.

Paragraph 0081; 0088; 0089; 0090, (2017/08/24)
The present invention relates to a novel compound. Especially, the novel compound ensures easy hole injection properties by forming easily hole-injectable highest occupied molecular orbital (HOMO) by containing at least two arylamine groups when applied to organic light-emitting devices, and exhibits excellent hole transferability as well as high glass transition temperature (Tg). Additionally, owing to excellent molecular arrangement in thin film, mobility increases, and low driving voltage, low power consumption, high efficiency, and long lifespan can be achieved as well.COPYRIGHT KIPO 2017
