Abstract

The invention relates to a pyrene-containing organic compound and application in OLED, and belongs to the technical field of semiconductors, wherein the 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 used asa functional layer material of an OLED light-emitting device, exciton utilization rate and high fluorescence radiation efficiency can be effectively improved, efficiency roll-off under high current density is reduced, device voltage is reduced, current efficiency of the device is improved, and service life of the device is prolonged.

Description

Technical field [0001] The present invention relates to the field of semiconductor technology, in particular to an organic compound containing pyrene and its application to OLED. Background technique [0002] Organic Light Emission Diodes (OLED: Organic Light Emission Diodes) device technology can be used to manufacture new display products as well as new lighting products. It is expected to replace the existing liquid crystal display and fluorescent lighting, and has a broad 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 purpose 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 functional material fi...
