Problems solved by technology

The first-generation cathode ray tube (CRT) display has withdrawn from the stage of history due to its large size, heavy weight, high power consumption, and inconvenient portability.
At present, the mainstream of flat panel display is liquid crystal display (LCD), but due to passive light emission, narrow viewing angle, and poor temperature adaptability, the response speed will be greatly reduced at low temperature, and even cannot operate. Obviously, these shortcomings make it difficult for LCD to meet modern information requirements. development needs

Embodiment A

[0046] (A1) Preparation of intermediate C1

[0047]

[0048] To 9-aminoanthracene ( 35.3 g, 183 mmol) and bromobenzene (59.9 g, 384 mmol) in degassed toluene (500 mL), and the mixture was heated at reflux for 2 hours. The reaction mixture was cooled to room temperature, diluted with toluene and filtered through celite. The filtrate was diluted with water and extracted with toluene, and the combined organic phases were evaporated under vacuum. The residue was filtered through silica gel (heptane / dichloromethane) and crystallized from isopropanol. The resulting solid (46.2 g, 134 mmol) and NBS (28.6, 161 mmol) were dissolved in a mixed solution of DMF and chloroform (1:3, 60 mL), stirred at room temperature for 6 hours, added water and extracted with dichloromethane, and dried the organic phase. Concentration and crystallization from isopropanol gave intermediate C1 (45.3 g, 80% of theory).

Abstract

The invention provides an aromatic amine derivative, and a preparation method and the application of the aromatic amine derivative, and relates to the technical field of organic optoelectronic materials. Through the design of molecular structure optimization, the aromatic amine derivative provided by the invention has an excellent hole transmitting capacity and can be used for preparing an organic light-emitting device, and particularly by serving as the hole transmitting material of the organic light-emitting device, the aromatic amine derivative shows advantages of high efficiency and long service life, which are superior than those of a conventionally used OLED (Organic Light Emitting Diode) device. The invention further provides a preparation method of the aromatic amine derivative, and the preparation method is simple and raw materials are easy to access.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to an aromatic amine derivative and its preparation method and application. Background technique [0002] After entering the 21st century, people need a new generation of flat-panel displays with better performance and better meet the needs of future life to meet the "4C", that is, computers, communications, and consumer electronics. Electronics), automotive electronics (car electronics) and "3G" (that is, the third generation mobile phone) era is coming, especially the future trend is to transmit a large amount of information and images on a lightweight carrier. The first-generation cathode ray tube (CRT) display has withdrawn from the stage of history due to its large size, heavy weight, high power consumption, and inconvenient portability. At present, the mainstream of flat panel display is liquid crystal display (LCD), but due to passive light emission, ...
