Problems solved by technology

[0007] At present, aromatic amine compounds are mostly used on the hole transport side, but the devices made of these materials still have the problems of high voltage and short life. Therefore, improving the life of blue light devices and reducing the device voltage are still problems that we need to overcome.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an aromatic amine derivative and its application. 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. As a current device, when a voltage is applied to the electrodes at both ends of the OLED light-emitting device, and the positive and negative charges in the organic layer functi...
