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, liquid crystal display devices are about to be replaced by organic electroluminescent devices because their performance cannot meet people's needs. Organic electroluminescent devices (OLEDs) have many advantages such as low energy consumption, self-luminescence, wide viewing angle, low cost, wide temperature range, fast response speed, continuously adjustable luminous color, flexible display, and relatively simple process. In recent years, organic electroluminescent technology has also developed rapidly.

[0003] The electroluminescence process of organic electroluminescent devices is an energy transfer process, which converts electrical energy into light energy. Voltage is applied to both ends of the device, and the electric field generated by this voltage causes electrons to be injected from the cathode of the device into the electron transport layer, while holes are injected from the anode of the device into the hole transport layer. The two carriers migrate into the light-emitting layer and combine to form excitons, which then emit light through radiation recombination.

[0004] Organic electroluminescent devices are composed of cathodes, anodes, and organic layers, among which the organic functional layers mainly include: hole transport layer, electron blocking layer, light-emitting layer, electron transport layer, hole blocking layer, covering layer, etc. In addition, the stacked OLED device includes a charge generation layer, which can connect two or more light-emitting units in series.

[0005] The hole transport layer can effectively transfer holes to the light-emitting layer to achieve light emission. At the same time, the hole transport layer can also help improve the charge injection efficiency, thereby improving the device's light-emitting efficiency and extending its service life. The cover layer can reduce the light loss reflected by nearby electrodes during light emission, thereby improving the device's light-emitting efficiency and extending its service life. The charge generation layer in the stacked OLED device can inject electrons into the bottom device and holes into the top device, respectively, achieving independent light emission for each light-emitting unit, greatly improving current efficiency and extending device service life.

[0006] It is worth considering how to develop more suitable hole transport materials, hole blocking layer materials, covering layer materials, and charge generation layer materials to improve the luminous efficiency and service life of organic electroluminescent devices. Summary of the invention

[0007] In order to solve the above problems, the present invention aims to provide an aromatic amine compound and an organic electroluminescent device thereof, which can improve the luminous efficiency of the organic electroluminescent device and extend the service life of the device.
