Abstract We report the use of a template and functional monomers in the synthesis of three novel polysulfonamide gels with new architectures and functional groups. These mesoporous polysulfonamide gels were prepared by the condensation polymerization of benzene-1,3-disulfonyl chloride (as the main precursor), linear monomers, and cross-linkers (as variable precursors) in the presence of a silica template by a combination of sol-gel chemistry and the nanocasting technique. In this synthesis pathway, in situ polymerization onto the template surface led to the construction of a silica/polymer nanocomposite. Next, after removal of the template, the nanocomposite gels were transformed into mesoporous polysulfonamide nanospheres. After the physicochemical identification of the synthesized materials, functionalized polysulfonamides were used as reusable novel catalysts with high efficiency for the Strecker reaction under mild conditions. These polymers have Bronsted/Lewis acid active sites, a mesoporous structure, and hydrogen bonding. Moreover, since these polymers are hydrogels that can absorb water, they can promote the Strecker reaction through chemical absorption of the generated water as a driving force. Overall, this article describes a novel synthesis procedure and application of porous polysulfonamide gels.

具有催化活性的亲水性多孔聚磺酰胺凝胶的靶向开发

摘要 我们报告了模板和功能单体在合成三种具有新结构和官能团的新型聚磺酰胺凝胶中的应用。这些介孔聚磺酰胺凝胶是通过苯-1,3-二磺酰氯（作为主要前体）、线性单体和交联剂（作为可变前体）在硅胶模板存在下通过溶胶的组合缩聚制备的。 -凝胶化学和纳米浇铸技术。在该合成途径中，模板表面上的原位聚合导致了二氧化硅/聚合物纳米复合材料的构建。接下来，去除模板后，纳米复合凝胶转化为介孔聚磺酰胺纳米球。合成材料经理化鉴定后，功能化聚磺酰胺被用作可重复使用的新型催化剂，在温和条件下高效地用于 Strecker 反应。这些聚合物具有布朗斯台德/路易斯酸活性位点、介孔结构和氢键。此外，由于这些聚合物是可以吸水的水凝胶，它们可以通过化学吸收生成的水作为驱动力来促进斯特雷克反应。总体而言，本文描述了多孔聚磺酰胺凝胶的新型合成程序和应用。它们可以通过化学吸收生成的水作为驱动力来促进 Strecker 反应。总体而言，本文描述了多孔聚磺酰胺凝胶的新型合成程序和应用。它们可以通过化学吸收生成的水作为驱动力来促进 Strecker 反应。总体而言，本文描述了多孔聚磺酰胺凝胶的新型合成程序和应用。
