Description

Aromatic amine compound and organic electroluminescent device thereof Technical Field The invention relates to the technical field of organic photoelectric materials, in particular to an arylamine compound and an organic electroluminescent device thereof. Background An Organic LIGHT EMITTING Diode (OLED) is an emerging display technology after CRT and LCD, and has become a research hot spot in the fields of display and illumination by virtue of its self-luminescence, high contrast, wide viewing angle, etc. The device is essentially of a film stacking structure and is composed of electrodes and organic functional material layers between the electrodes, and the luminous principle is that carriers in the organic functional layers are injected and compounded in the luminous layers under the drive of an electric field, so that the conversion from electric energy to light energy is completed. The method is widely applicable to the manufacture of products such as novel display panels, high-efficiency lighting lamps and the like. Although OLED technology has significant advantages, in practical production and application, the comprehensive performance of the OLED is still limited by the materials of the functional layers, and the organic layers of the OLED include a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, a cover layer, etc., where the performance of the cover layer material is particularly critical. The coating layer not only affects the carrier transport efficiency, but also plays a decisive role in the light extraction effect of the light-emitting layer. The organic materials of the OLED coating layer on the market generally have core defects, wherein the short plate with the light extraction related performance is particularly outstanding, the suitability of the optical parameters such as refractive index and light transmittance of the existing material and other film layers of the device is poor, the internal light loss cannot be effectively restrained, the light extraction efficiency is low, a large amount of light energy is blocked in the device to directly influence the light-emitting brightness of the device, and even if partial materials try to optimize the optical parameters, the problem of insufficient chemical stability is caused, and further chain reactions such as insufficient charge recombination, shortened service life of the device and the like are caused. These technical bottlenecks greatly limit the large-scale application of OLED technology in core fields such as high-end display and high-efficiency illumination. Therefore, developing a capping layer organic material with a good refractive index, which can significantly improve the light extraction efficiency, so as to break through the bottleneck of the prior art and optimize the overall performance of the OLED device has become an urgent need in the art.
