Description
technical field [0001] The invention relates to the technical field of semiconductors, in particular to a compound material containing fluorene as a central skeleton and its application in the field of OLEDs. 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, a...
