Paragraph 0139-0143, (2020/09/16)
The invention provides a fluorene compound and an electronic device. According to the invention, by introducing a fluorene rigid structure, the fluorene compound provided by the invention has excellent film-forming property and thermal stability, and can be used for preparing organic electroluminescent devices, organic field effect transistors and organic solar cells; the fluorene compound can beused as a constituent material of a hole injection layer, a hole transport layer, a light emitting layer, an electron blocking layer, a hole blocking layer or an electron transport layer, and can reduce the driving voltage, improve the efficiency, improve the brightness, prolong the service life and the like; more importantly, the fluorene compound provided by the invention can effectively isolatea donor group from an acceptor group, so that the fluorene compound is an ideal skeleton for constructing a thermal activation delayed fluorescence material; and the preparation method of the fluorene compound is simple, raw materials are easy to obtain, and industrial development requirements can be met.
