Description

technical field

[0001] The invention relates to the technical field of semiconductor materials, in particular to a compound with an ethylenic bond-containing seven-membered ring as the core, a preparation method thereof and an 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...
