Method for synthesizing 9,9'-spirobifluorene derivative

The invention relates to a method for synthesizing a 9,9'-spirobifluorene derivative, and belongs to the field of organic chemical synthesis. The method comprises the following steps: activating a C-Fbond in tetrahydrofuran under inert gas protection through reduction and lithiation reaction of raw materials of 2-fluorobiphenyl and a metal lithium sheet, thus establishing 2-biphenyl lithium; thenenabling the 2-biphenyl lithium to react with a fluorenone derivative, hydrolyzing, drying a solvent by distillation, and carrying out ring closing on solid in acetic acid, thus synthesizing the 9,9'-spirobifluorene derivative. According to the method disclosed by the invention, the 2-fluorobiphenyl in low cost is adopted as a raw material to replace 2-bromobiphenyl commonly adopted by a traditional method, the production cost is low, and reaction conditions are gentle; an applicable substrate range of the method is wide, and a new thought is provided for synthesis of the 9,9'-spirobifluorenederivative.

Spirobifluorene/sulfone hybrid: Highly efficient solution-processable material for UV-violet electrofluorescence, blue and green phosphorescent OLEDs

A high efficient UV-violet emission type material bis[4-(9,9′- spirobifluorene-2-yl)phenyl] sulfone (SF-DPSO) has been synthesized by incorporating electron deficient sulfone and morphologically stable spirobifluorene into one molecule. The steric and bulky compound SF-DPSO exhibits an excellent solid state photoluminescence quantum yield (ΦPL = 92%), high glass transition temperature (Tg = 211 °C) and high triplet energy (ET = 2.85 eV). In addition, the uniform amorphous thin film could be formed by spin-coating from its solution. These promising physical properties of the material made it suitable for using as UV-violet emitter in non-doped device and appropriate host in phosphorescent OLEDs. With SF-DPSO as an emitter, the non-doped solution processed device achieved an efficient UV-violet emission with the EL peak around 400 nm. By using SF-DPSO as a host, solution processed blue and green phosphorescent organic light emitting diodes showed a high luminous efficiency of 13.7 and 30.2 cd A-1, respectively.
