Abstract

The invention discloses a compound taking a triarylamine structure as a core as well as a preparation method and application of the compound. The structure of the compound is shown as a general formula (1). The compound provided by the invention has relatively high glass transition temperature and molecular thermal stability, proper HOMO and LUMO energy levels and relatively high mobility, and caneffectively improve the photoelectric property of an OLED device and prolong the service life of the OLED device by optimizing the structure of the device.

Description

technical field [0001] The invention relates to the technical field of organic electroluminescent materials, in particular to a compound containing triarylamine in its structure and a preparation method thereof. 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. [0003] 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 light-emitting device...
