研究了以[Ph3P=N−PPh3]+[Hf2]−为催化剂的双烷基磺酰氟化物(AA单体)与双酚双(叔丁基二甲基硅基)醚(BB单体)的SuFex型缩聚反应。AA单体是通过高可靠的乙烯磺酰氟与胺/苯胺的Michael加成反应得到的，而BB单体是通过双酚与叔丁基二甲基硅氯硅烷的硅基化反应得到的。通过这些反应，通过利用容易获得的胺、苯胺和双酚作为起始原料，实现了显著多样化的单体构建块。基于SuFEx的聚磺酸盐形成反应表现出极高的效率和官能团耐受性，在>；99 %的转化率下可在10 分钟到1 h内生成各种侧链官能化的聚磺酸盐。当侧链上含有正交基时，聚磺酸盐可以通过基于点击化学的后聚合修饰来进一步官能化。
The SuFEx‐based polycondensation between bisalkylsulfonyl fluorides (AA monomers) and bisphenol bis(t‐butyldimethylsilyl) ethers (BB monomers) using [Ph3P=N−PPh3]+[HF2]−as the catalyst is described. The AA monomers were prepared via the highly reliable Michael addition of ethenesulfonyl fluoride and amines/anilines while the BB monomers were obtained from silylation of bisphenols byt‐butyldimethylsilyl chloride. With these reactions, a remarkable diversity of monomeric building blocks was achieved by exploiting readily available amines, anilines, and bisphenols as starting materials. The SuFEx‐based polysulfonate formation reaction exhibited excellent efficiency and functional group tolerance, producing polysulfonates with a variety of side chain functionalities in >99 % conversion within 10 min to 1 h. When bearing an orthogonal group on the side chain, the polysulfonates can be further functionalized via click‐chemistry‐based post‐polymerization modification.
