Abstract
The invention relates to an organic compound containing benzanthracene fluorene and diarylamine, and application of the organic compound in an organic electroluminescent device, belongs to the technical field of semiconductors, and provides a compound with a structure shown as a general formula (1). The invention also discloses application of the organic compound containing benzanthracene fluoreneand diarylamine. The compound provided by the invention has relatively strong hole transport capability, improves the hole injection and transport performance under a proper HOMO energy level, and achieves the electron blocking effect under the proper LUMO energy level so as to improve the recombination efficiency of excitons in the light-emitting layer. When the 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 rangeof the invention.
Description
technical field [0001] The invention relates to the technical field of semiconductors, in particular to an organic compound containing benzanthracene fluorene and diarylamine 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 fil...
