Abstract

The invention discloses an arylamine derivative and an organic light-emitting device, and relates to the technical field of organic photoelectric materials. The arylamine derivative is an electron-rich system, and has a large conjugation structure, and hole transport performance is good. In addition, the light refraction index of the arylamine derivative is high, and when the arylamine derivativeis used as a light taking-out layer of the organic light-emitting device, the light exiting efficiency of the device can be improved effectively. In addition, the arylamine derivative has a large rigid structure due to introduction of large-size triphenylene, the glass transition temperature and thermal stability of the material are improved effectively, and film forming of the material is facilitated. The organic light-emitting device comprises an anode, a cathode and an organic matter layer, and the organic matter layer is positioned between the anode and the cathode, and comprises the arylamine derivative. The organic light-emitting device has low driving voltage, high light-emitting efficiency and long service life.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to an aromatic amine derivative and an organic electroluminescence device thereof. Background technique [0002] Organic optoelectronic materials are organic materials with photon and electron generation, conversion and transport properties. Currently, organic photoelectric materials have been applied to organic electroluminescent devices (Organic Light-Emitting Diode, OLED). OLED refers to a device in which organic photoelectric materials emit light under the action of current or electric field, which can directly convert electrical energy into light energy. In recent years, OLED as a new generation of flat panel display and solid-state lighting technology is receiving more and more attention. Compared with liquid crystal display technology, OLED is more and more used in the field of display and lighting due to its low power consumption, active light emiss...
