Description

Technical Field

[0001] The invention relates to the technical field of organic photoelectric materials, and in particular to an aromatic amine compound and an organic electroluminescent device thereof. Background Art

[0002] With the continuous development of society, science and technology are also developing continuously, which has brought about a new round of revolution in the way of information dissemination. Among them, display technology has experienced a qualitative leap in just over a decade. At present, liquid crystal displays dominate the market, but as people's requirements for display performance increase, the shortcomings of liquid crystal display technology are gradually reflected. As a new generation of display equipment, organic electroluminescent devices OLED have attracted people's attention with excellent characteristics such as thin body, light weight, high brightness, high definition, fast response, low voltage, high efficiency, long life, and low cost.

[0003] Organic electroluminescence can be summarized as the following processes: (1) Carrier injection (2) Carrier transport (3) Electron and hole collision to form excitons (4) Exciton radiation recombination to emit light. The functional layers in organic electroluminescent devices can be divided into hole injection layer, hole transport layer, luminescent auxiliary layer, electron blocking layer, luminescent layer, hole blocking layer, electron transport layer, electron injection layer, covering layer, charge generation layer, etc. Among them, the hole transport layer material not only requires it to have a high hole mobility but also has a suitable HOMO energy level to ensure the effective injection and transmission of holes between the electrode / organic layer and the organic layer / organic layer interface; the covering layer material is located on the top of the cathode, which can help reduce the light loss caused by reflection from the nearby electrode during light emission, further improve the device's luminous efficiency and extend its service life; the stacked device connects the light-emitting layer in series through the charge generation layer material, and the current efficiency increases exponentially with the number of series-connected devices. Under the same initial brightness conditions, the service life of the stacked device will be longer than that of the traditional OLED device.

[0004] Therefore, how to develop hole transport materials, covering layer materials, and charge generation layer materials with better performance, so as to improve the luminous efficiency and extend the service life of organic electroluminescent devices is a question worth considering.
