Abstract

The invention discloses amine derivatives and an OLED (organic light-emitting diode) containing the same, and relates to the technical field of organic optoelectronic materials. The amine derivativesare of an electron-rich system, have larger conjugated structure and show better hole transport performance. Besides, the amine derivatives have higher light refractive index, and can effectively increase luminous efficiency of the device when used as an optical extraction layer of the OLED. Furthermore, the amine derivatives have larger rigid structure due to introduction of large triphenylene, glass transition temperature and heat stability of the material are increased effectively, and film forming of the material is facilitated. The OLED comprises an anode, a cathode and an organic matterlayer, wherein the organic matter layer is located between the anode and the cathode and contains the amine derivatives. The OLED has lower driving voltage, higher luminous efficiency and longer service life.

Description

Technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to an amine derivative and an organic electroluminescent device thereof. Background technique [0002] Organic photoelectric materials are organic materials that have the characteristics of photon and electron generation, conversion and transmission. At present, organic photoelectric materials have been applied to 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. It can directly convert electrical energy into light energy. In recent years, OLED has received more and more attention as a new generation of flat panel display and solid-state lighting technology. Compared with liquid crystal display technology, OLED is more and more used in display and lighting fields because of its low power consumption, active light emission, fast response speed, high contr...
