| titleOfInvention | A kind of preparation method and application of double-cable polymer |
| abstract | A preparation method and application of a double-cable polymer, wherein the double-cable polymer is a benzodithiophene dione-benzodithiophene-type double-cable polymer structural formula as shown in the abstract drawings. The preparation method of the double-cable polymer includes the following steps: (1) adding the benzodithiophene substituted by dialkyl bromide and the acceptor nucleophile into an organic solvent, and adding potassium carbonate after the equilibrium is dissolved; after heating and cooling Add chloroform and deionized water; liquid separation, washing, drying, and rotary evaporation to obtain a crude product; (2) adding the crude product and benzodithiophene diketone double tin reagent to toluene and N,N-bistin according to a certain proportion In methylformamide, after the solution is degassed, palladium catalyst and triphenylphosphine are added; after the reaction, the product is precipitated with methanol and filtered; the filter cake is extracted with a solvent, filtered through a filter membrane, and vacuum-dried to obtain a black polymer product. The double-cable polymer of the invention has excellent optoelectronic properties, and can be used as an organic semiconductor material in single-component organic solar cell materials and the like. |
