Abstract

The invention discloses an organic compound and an application thereof to an OLED (organic light emission diode) device. The organic compound contains dibenzo six-membered rings, and oxygen atoms, sulfur atoms, C1-10 linear or branched alkyl substituted alkylidene, aryl substituted alkylidene and alkyl or aryl substituted tertiary amide are contained between the two dibenzo six-membered rings. Thecompound has higher glass transition temperature and molecular thermal stability and appropriate HOMO and LUMO energy level, and photoelectric property of the OLED device can be effectively improvedand the service life of the OLED device can be effectively prolonged through structural optimization of the device.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a compound material containing a dibenzo six-membered ring structure as a central skeleton and its application in the field of OLEDs. 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. As a current device, when a voltage is applied to the electrodes at both ends of the OLED ligh...
