Abstract

The invention relates to a pyrene-containing organic compound and application thereof, and belongs to the technical field of semiconductors, wherein structure of the compound is represented by a general formula (1). The compound provided by the invention has relatively strong hole transport capability, and the hole injection and transport performance is improved under a proper HOMO energy level; under the proper LUMO energy level, the electron blocking effect is achieved, and the recombination efficiency of excitons in the light-emitting layer is improved; and when the compound is applied to an OLED device, high film layer stability can be kept through device structure optimization, the photoelectric property of the OLED device can be effectively improved, and the service life of the OLEDdevice can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a pyrene-containing organic compound 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 laye...
