Entangled structures have fascinated scientists for both their artistic beauty and functional properties. Zhang and co-workers have recently reported, in the Journal of the American Chemical Society, the synthesis of a cinquefoil knot in which metal coordination sites can be tuned using post-synthetic protocols, providing a way to edit the skeletons of topological molecules in order to endow them with otherwise inaccessible functions.

纠缠支架上金属配位的合成后调整


纠缠结构因其艺术美感和功能特性而让科学家着迷。Zhang 及其同事最近在《美国化学学会杂志》（Journal of the American Chemical Society） 上报道了五叶结的合成，其中金属配位点可以使用合成后协议进行调整，提供了一种编辑拓扑分子骨架的方法，以便赋予它们原本无法获得的功能。
