Abstract

The invention relates to an organic compound and a preparation method thereof, and application in OLED, and belongs to the technical field of semiconductors, wherein the structure of the compound is represented by a general formula (1). The invention also discloses a preparation method and application of the compound. According to the invention, the compound provided by the invention has high glass transition temperature and molecular thermal stability, is low in absorption in the field of visible light, is high in refractive index, can effectively improve the light extraction efficiency of anOLED device after being applied to the CPL layer of the OLED device, also has a deep HOMO energy level and high electron mobility, and can be used as a hole barrier, an electron transport layer or alight-emitting layer material of an OLED device to balance the balance degree of electrons and holes in a light-emitting layer, so that the recombination efficiency of the holes and the electrons in the light-emitting layer is improved so as to improve the light-emitting efficiency and the service life of the OLED device.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an organic compound, its preparation method and its application in OLED. Background technique [0002] Organic electroluminescent (OLED: Organic Light Emission Diodes) device technology can be used to manufacture new display products and also can be used to make new lighting products, which is expected to replace the existing liquid crystal display and fluorescent lighting, and has a wide application prospect. The OLED light-emitting device is like a sandwich structure, including electrode material film layers and organic functional materials sandwiched between different electrode film layers. Various functional materials are superimposed on each other according to the application to form an OLED light-emitting device. OLED light-emitting devices are current devices. When a voltage is applied to the electrodes at both ends, and the positive and negative charges in the orga...
