Abstract

The invention relates to an organic compound containing pyridine and an application thereof in an OLED device. The structure of the compound of the invention is as shown in the general formula (1): the compound has higher glass transition temperature and molecular thermal stability; in the visible light field, the absorption is low and the refractive index is high. After the organic compound is applied to the CPL layer of the OLED device, the light extraction efficiency of the OLED device can be effectively improved. The compounds of the present invention also have deep HOMO levels and high electron mobility, The organic compound can be used as a hole blocking / electron transport layer material of the OLED device, holes or energy can be effectively blocked from being transferred from the light emitting layer to the electron layer side, thereby improving the recombination efficiency of holes and electrons in the light emitting layer, and further improving the light emitting efficiency and 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 containing azabenzene and its application in an organic electroluminescent device. 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 an...
