Abstract

The invention provides a silafluorene-containing aromatic amine compound and an organic electroluminescent device thereof, and relates to the technical field of organic photoelectric materials. The aromatic amine compound containing silicon fluorene has the characteristics of strong electron donating ability, high hole mobility, high glass transition temperature, high thermal stability and low probability of crystallization when heated and cooled. When the compound is applied to a covering layer or a hole transport layer of an OLED device, the light extraction efficiency, the service life and the luminous efficiency of the OLED device can be effectively improved, and the problems of low refractive index, low glass transition temperature, poor thermal stability, easiness in aggregation and crystallization and the like in the existing material can be solved.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to an aromatic amine compound containing silicon fluorene and 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 new lighting products, and 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 charg...
