Although items exhibiting topology are ubiquitous in everyday life, the realization of topology at the nanoscale level relies on innovative synthetic strategies. A molecular weaving strategy, recently reported in Nature Chemistry and Nature by Leigh and co-workers, has outlined the precise synthesis of a molecular 7₄ knot and a two-dimensional molecular fabric. These breakthroughs hard on the heels of each other open up a new route for incorporating predictable, well-defined topologies into molecular architectures. They will fuel the exploitation of advanced materials with topology-related properties.

在分子尺度上编织

尽管展示拓扑的项目在日常生活中无处不在，但纳米级拓扑的实现依赖于创新的合成策略。Leigh 及其同事最近在《自然化学》和《自然》杂志上报道了一种分子编织策略，概述了分子 7 ₄结和二维分子织物的精确合成。这些紧随其后的突破为将可预测的、定义明确的拓扑结构整合到分子结构中开辟了一条新途径。它们将推动具有拓扑相关特性的先进材料的开发。
