carboxylase mimics. Lewis pair polymers containing bulky Lewis acidic and basic groups as the precursor, can bind CO2 to drive an intramolecular folding into SCNPs, in which CO2 as the folded nodes can form gas‐bridged bonds. Such bridging linkages highly activate CO2, which endows the SCNPs with extraordinary catalytic ability that can not only catalyze CO2‐insertion of C(sp3)‐H for imitating the natural
在大气条件下模拟天然羧化酶转化CO 2的功能是一个巨大的挑战。在本文中,我们报告了一类CO 2折叠的单链纳米颗粒(SCNP),它们可以作为可循环利用的,功能增强的羧化酶模拟物。含有庞大的路易斯酸性和碱性基团作为前体的路易斯对聚合物可以结合CO 2从而驱动分子内折叠成SCNP,其中作为折叠节点的CO 2可以形成气桥键。这种桥联键可高度活化CO 2,这赋予SCNP具有非凡的催化能力,不仅能够催化C(sp 3的CO 2插入)-H模仿天然酶的功能,它还可以作用于C(sp 2和sp)-H底物的非天然羧化途径。纳米催化剂具有很高的催化效率和可回收性,并且可以在室温和接近环境CO 2的条件下工作,从而激发了可持续利用C 1的新方法。
