Paragraph 0092; 0094; 0095, (2018/01/11)
The invention discloses a bis S,S-dioxo-dibenzothiophene five-membered ring monomer, a preparation method thereof and a polymer. Due to a bis sulfonyl group in the bis S,S-dioxo-dibenzothiophene five-membered ring, the electron affinity of molecules can be improved more easily. By introducing an alkyl chain to the five-membered ring, the solubility of the monomer in organic solvent can be significantly improved, and meanwhile the steric hindrance influence on polymerization reaction from the position of the alkyl chain can be avoided. Due to a large conjugate plane, the cavitation and electron transmission performance of the polymer can be improved. Through Suzuki or Stille or Yamamotor polymerization reaction of the bis S,S-dioxo-dibenzothiophene five-membered ring monomer, a homopolymer or copolymer can be obtained. The polymer of the series has good solubility in organic solvent and is suitable for solution processing. The bis S,S-dioxo-dibenzothiophene five-membered ring monomer has broad application prospects in the fields of organic light-emitting display, organic photovoltaic cells and organic field effect transistors.
