Abstract

The invention relates to a benzanthracene-containing organic compound and application thereof, and belongs to the technical field of semiconductors. The benzanthracene-containing organic compound hasa structure shown as 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 aproper 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; when thebenzanthracene-containing organic compound is used as a light-emitting functional layer material of an OLED light-emitting device, the exciton utilization rate and the radiation efficiency can be effectively improved by matching with the branched chains in the range of the invention.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an organic compound containing benzanthracene and an application thereof. Background technique [0002] Organic electroluminescent device technology can be used to manufacture new display products and new lighting products. It 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 functional material film are acted on by the ele...
