Sulfur(vi) fluoride exchange (SuFEx) is a category of click chemistry that enables covalent linking of modular units through sulfur(vi) connective hubs. The efficiency of SuFEx and the stability of the resulting bonds have led to polymer chemistry applications. Now, we report the SuFEx click chemistry synthesis of several structurally diverse SOF₄-derived copolymers based on the polymerization of bis(iminosulfur oxydifluorides) and bis(aryl silyl ethers). This polymer class presents two key characteristics. First, the [–N=S(=O)F–O–] polymer backbone linkages are themselves SuFExable and undergo precise SuFEx-based post-modification with phenols or amines to yield branched functional polymers. Second, studies of individual polymer chains of several of these new materials indicate helical polymer structures. The robust nature of SuFEx click chemistry offers the potential for post-polymerization modification, enabling the synthesis of materials with control over composition and conformation.

Sulfur( vi ) 氟化物交换 (SuFEx) 是一种点击化学，可通过硫( vi ) 连接枢纽实现模块化单元的共价连接。SuFEx 的效率和所得键的稳定性已导致聚合物化学应用。现在，我们报告了几种结构多样的 SOF _{4的 SuFEx 点击化学合成}基于双（亚氨基二氟化硫）和双（芳基甲硅烷基醚）聚合的衍生共聚物。该聚合物类别具有两个关键特性。首先，[–N=S(=O)F–O–] 聚合物主链键本身是 SuFExable，并经过精确的基于 SuFEx 的酚类或胺类后改性以产生支化的功能聚合物。其次，对其中几种新材料的单个聚合物链的研究表明了螺旋聚合物结构。SuFEx 点击化学的稳健性质提供了聚合后修饰的潜力，从而能够合成具有对成分和构象的控制的材料。
