Bifluoride salt reported by K. Barry Sharpless, and colleagues as a catalyst for sulfur(VI) fluoride exchange (SuFEx,)-based AA-BB polycondensation reactions to prepare polysulfonates with diverse structures, narrow polydispersity, and excellent thermal and hydrolytic stability. Bisalkylsulfonyl fluorides, the AA monomers, were prepared from ethenesulfonyl fluoride (746959,) and amines/anilines while bisphenol bis(t-butyldimethylsilyl) ethers, the BB monomers, were synthesized using tert-butyldimethylsilyl chloride (190500,) and bisphenols. Varying the amines, anilines, and bisphenols results in assorted polymeric backbones, including those bearing orthogonal side chains for modification post-polymerization (e.g. by CuAAC). Reaction is amenable to scale up.
