Abstract

Macroscopic weaving has been proven to be the most enduring and effective method for manufacturing fabrics to meet the practical needs of humanity for thousands of years. However, the construction of molecular structures with exquisite topologies and specific properties based on molecular weaving is still in its infancy. Herein, we designed and fabricated a two-dimensional (2D) woven covalent organic polymer (COP) network (named as CityU-46) driven by the dative N→B bonds between the 1,4-bis(benzodioxa-borole)benzene (BACT) and 2,5-bis(4-pyridyl)-1,3,4-thiadiazole (BPT). The complex woven topology of CityU-46 was determined using single crystal X-ray diffraction technique, revealing that it features a well-defined two-over and two-under interweaving pattern at the molecular level. Due to its structural merits, CityU-46 can be used as an artificial organic solid-electrolyte interphase layer on the surface of Li metal anodes, significantly improving the stability and long-term performance of lithium metal cells.

共价有机聚合物链交织成二维网络：合成、单晶结构及其在稳定锂金属阳极中的应用

宏观织造已被证明是千百年来最持久、最有效的制造织物的方法，以满足人类的实际需要。然而，基于分子编织构建具有精致拓扑和特异性能的分子结构仍处于起步阶段。在此，我们设计并制备了一个二维（2D）编织共价有机聚合物（COP）网络（命名为citu -46），该网络由1,4-双（苯并二氮杂）苯（BACT）和2,5-双（4-吡啶基）-1,3,4-噻二唑（BPT）之间的N→B键驱动。利用单晶x射线衍射技术确定了CityU-46的复杂编织拓扑结构，揭示了其在分子水平上具有明确的两上两下交织模式。由于其结构上的优点，CityU-46可以作为人造有机固-电解质间相层在锂金属阳极表面，显著提高锂金属电池的稳定性和长期性能。
