We report the convenient synthesis of a benzobis(imidazolium)-embedded conjugated polyelectrolyte pBBI by a Cu-catalyzed direct C?H arylation of a cationic benzobis(imidazolium) monomer with a diiodide comonomer. pBBI shows weak fluorescence in solution due to rotation of the repeat units in the conjugated backbone, and enhanced fluorescence when electrostatically interacting with a variety of anions to form aggregates. Specially, pBBI responds to the bisulfite anion with intensified unique deep-blue fluorescence easily discriminated by naked eye.

Paragraph 0024; 0025; 0026, (2020/01/12)
The invention provides a synthetic method of a pesticide intermediate for synthesizing flumioxazin, and belongs to the field of pesticide synthesis. The synthetic method solves the problem that the yield of existing synthetic 7-fluoro-6-amino-2H-1,4-benzoxazine-3(4H)-one is not high. The synthetic route of the synthetic method of the pesticide intermediate for synthesizing flumioxazin is shown inthe specification, and the yield is high.
