The invention provides a fluorene spirotriphenylamine compound, an organic electronic device and a display device or an electronic device. The fluorene spirotriphenylamine compound is introduced into a rigid structure of fluorene spirotriphenylamine to make it excellent in film-forming properties and thermal stability, and can be used to prepare Organic electroluminescent devices, organic field effect transistors and organic solar cells. In addition, the fluorene spirotriphenylamine compound of the present invention can be used as a constituent material of the hole injection layer, the hole transport layer, the light emitting layer, the electron blocking layer, the hole blocking layer or the electron transport layer, which can reduce the driving voltage and improve the efficiency and brightness. and lifespan etc. More importantly, the fluorene spirotriphenylamine compound of the present invention can effectively isolate donor and acceptor groups, so it is an ideal framework for constructing thermally activated delayed fluorescent materials. The preparation method of the fluorene spirotriphenylamine compound of the invention is simple, and the raw materials are easy to obtain, which can meet the development demand of industrialization. |
