The invention relates to a compound of a white light high-mobility material 2-fluorenanthracene derivative, a preparation method, and an application in an organic photoelectric device as a p-type organic semiconductor material and a light-emitting material. The compound structures of 2‑fluorenanthracene derivatives are shown below: In the formula, R 1 -R 9 may be the same or different, independently selected from hydrogen, deuterium or a C1-C20 long alkyl chain, X is C, S or O, R 10 -R 11 may be the same or different, independently selected from From hydrogen, deuterium, C1-C20 long alkyl chain, double bond oxygen, or R 10 , R 11 and fluorene are jointly connected to form 9,9'-spirobifluorene. The material has good thermal stability and air stability, and the material can be manufactured in one pot, which is suitable for industrial production; the material has strong luminescence, and can emit near pure white light in OLEDs, and has excellent charge at the same time The transport properties can be applied in organic white light-emitting transistor devices to realize self-driven OLED lighting or display. |
