Abstract

The invention relates to an organic compound taking triazine and benzimidazole as cores and application thereof to an OLED (Organic Light Emitting Diode) device. The compound provided by the invention has relatively high glass transition temperature and molecule thermal stability; the compound has low absorption and high refractive index in the field of visible light; after the compound is applied to a CPL (Circular Polarizing Filter) layer of an OLED device, the light extraction efficiency of the OLED device can be effectively improved; the compound also has a deep HOMO energy level and high electron mobility and can be used as a hole-blocking / electron transferring layer material of the OLED device; and the compound can be used for effectively stopping a hole or energy from being transmitted to one side of an electron layer from a light emitting layer, so that the compounding efficiency of the hole and electrons on the light emitting layer is improved, and furthermore, the luminous efficiency of the OLED device is improved and the service life of the OLED device is prolonged.

Description

technical field

[0001] The invention relates to the technical field of semiconductors, in particular to an organic compound with triazine and benzimidazole as the core and its application in organic electroluminescent devices. 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,...
