Abstract

The invention relates to an organic compound with benzene as a core and application of the organic compound, belonging to the technical field of semiconductors. The structure of the compound providedby the invention is shown as a general formula (1) in the specification. The compound provided by the invention has relatively strong hole transport capacity; hole injection and transport performanceis improved under a proper HOMO energy level; and under a proper LUMO energy level, electron blocking effect is achieved, and the recombination efficiency of excitons in a light-emitting layer is improved. When the compound is applied to an OLED device, high stability of a film layer can be kept through structure optimization of the device, the photoelectric property of the OLED device can be effectively improved, and the service life of the OLED device can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an organic compound with homobenzene as the core 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 ...
