Abstract

The invention discloses a compound taking an anthrone skeleton as a core, and application thereof, and belongs to the technical field of semiconductors. The structure of the compound provided by the invention is represented by general formula (1) shown in the specification. The compound provided by the invention has relatively high triplet state energy level, relatively high glass transition temperature and relatively high molecular thermal stability; and when the material is used as a light-emitting layer or a hole blocking layer or an electron transport layer material of an OLED light-emitting device, the light-emitting efficiency of the device can be effectively improved, and the service life of the device can be effectively prolonged.

Description

technical field [0001] The invention relates to a compound with anthrone skeleton as the core and application thereof, belonging to the technical field of semiconductors. Background technique [0002] Organic Light Emission Diodes (OLED) device technology can be used not only to manufacture new display products, but also to make new lighting products. It 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 organic layer functional material film are ...
