Unlike inorganic crystals, metal-organic frameworks do not have a well-developed nanostructure library, and establishing their appropriately diverse and complex architectures remains a major challenge. Here, we demonstrate a general route to control metal-organic framework structure by a solvent-assisted ligand exchange approach. Thirteen different types of metal-organic framework structures have been prepared successfully. To demonstrate a proof of concept application, we used the obtained metal-organic framework materials as precursors for synthesizing nanoporous carbons and investigated their electrochemical Na+ storage properties. Due to the unique architecture, the one-dimensional nanoporous carbon derived from double-shelled ZnCo bimetallic zeolitic imidazolate framework nanotubes exhibits high specific capacity as well as superior rate capability and cycling stability. Our study offers an avenue for the controllable preparation of well-designed meta-organic framework structures and their derivatives, which would further broaden the application opportunities of metal-organic framework materials.

溶剂辅助的配体交换方法使金属有机框架具有多样化和复杂的结构。
与无机晶体不同，金属有机框架没有完善的纳米结构库，建立其适当多样化和复杂的结构仍然是一个重大挑战。在这里，我们展示了通过溶剂辅助配体交换方法控制金属有机骨架结构的一般途径。已成功制备了13种不同类型的金属有机骨架结构。为了证明概念应用，我们使用所获得的金属有机骨架材料作为合成纳米多孔碳的前体，并研究了它们的电化学 Na+ 存储性能。由于其独特的结构，由双壳ZnCo双金属沸石咪唑盐骨架纳米管衍生的一维纳米多孔碳表现出高比容量以及优异的倍率性能和循环稳定性。我们的研究为可控制备精心设计的元有机骨架结构及其衍生物提供了一条途径，这将进一步拓宽金属有机骨架材料的应用机会。
