Problems solved by technology

However, the properties of aromatic amine compounds with different structures are also different. For example, in aromatic amine compounds, the difference in the group directly connected to N will produce different degrees of electronic effects (including inductive effects and conjugation effects), The hole transport ability, HOMO and T1 value of the compound are different

Abstract

The invention relates to the technical field of organic photoelectric materials, in particular to a triarylamine compound and an organic electroluminescent device thereof. The triarylamine compound shown in the formula (I) has good thermal stability and hole transport capacity, has more appropriate HOMO and T1 value compared with other functional layers, especially a light-emitting layer, and can improve the light-emitting efficiency of a device and prolong the service life of the device when being used as a hole transport layer or a light-emitting auxiliary layer; besides, the triarylamine compound shown in the formula (I) also has good solubility and can be applied to different device preparation processes, such as evaporation, ink-jet printing, spin coating and the like. The triarylamine compound shown in the formula (I) is matched with a covering layer material shown in the formula (V) and a doping material shown in the formula (VI) for use respectively or simultaneously, the luminous efficiency of the device is further improved, and the service life of the device is further prolonged.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to a triarylamine compound and an organic electroluminescence device thereof. Background technique [0002] Organic Light-Emitting Diode (hereinafter referred to as OLED) due to its small thickness, light weight, wide viewing angle, short response time, wide application temperature range, low energy consumption, high luminous efficiency, good color purity, and flexibility It has attracted the attention of many display companies, lighting companies and research institutions, and is regarded as the most promising display and lighting technology. [0003] The OLED device has a sandwich structure, including an outer metal cathode and an ITO anode, and an organic layer is sandwiched between the cathode and the anode. The organic layer is subdivided into a hole transport area, an electron transport area, and a light emitting area according to different functions. ...
