Spirobifluorene molecules have a non-planar spatial structure, the two fluorene monomers to sp3 hybrid C atoms as the center bridge together. The introduction of it into the molecules with electroluminescent properties has great application value for improving the thermal stability and spectral stability of the molecules. In this paper, we mainly introduce the research progress of spirobifluorene structure in molecular design of organic polymer electroluminescent materials in recent years, and give a brief prospect of the research prospects.
