The invention relates to the technical field of organic optoelectronic materials, in particular to a triarylamine compound and an organic electroluminescence device thereof. The triarylamine compound of formula (I) provided by the present invention has good thermal stability and hole transport ability, and has more appropriate HOMO and T1 values than other functional layers, especially the light-emitting layer, as a hole transporter layer or luminescence auxiliary layer, it can not only improve the luminous efficiency of the device, but also improve the service life of the device; in addition, the triarylamine compound described in formula (I) also has good solubility and can be used in the preparation of different devices In the process, such as evaporation, inkjet printing, spin coating, etc. In the present invention, the triarylamine compound of formula (I) is used in combination with the cover layer material shown in formula (V) and the doping material shown in formula (VI), respectively or simultaneously, the luminous efficiency and service life of the device are obtained. to further improve. |
