Metal-organic frameworks (MOFs) are crystalline porous materials characterized by their high porosity and chemical tailorability. To realize the full potential of synthesized MOFs, it is important to transform them from crystalline solid powders into materials with integrated morphologies and properties. One promising approach is facet-controlled assembly, which involves arranging individual crystalline MOF particles into ordered macroscale structures by carefully controlling the interactions between particles. The resulting assembled MOF structures maintain the characteristics of individual particles while also exhibiting improved properties overall. In this article, we emphasize the essential concepts of MOF assembly, highlighting the impact of building blocks, surface interactions, and Gibbs free energy on the assembly process. We systematically examine three methods of guiding facet-controlled MOF assembly, including spontaneous assembly, assembly guided by external forces, and assembly through surface modifications. Lastly, we offer outlooks on future advancements in the fabrication of MOF-based material and potential application exploration.
金属有机框架材料（MOFs）是一类具有高孔隙率和化学可定制性的晶体多孔材料。为了充分发挥合成MOFs的潜力，将它们从晶体固体粉末转变为具有集成形态和性能的材料至关重要。一种有前景的方法是晶面控制组装，即通过仔细控制颗粒间的相互作用，将单个晶体MOF颗粒排列成有序的宏观结构。所得的组装MOF结构保留了单个颗粒的特性，同时整体性能也有所提升。在本文中，我们强调了MOF组装的基本概念，突出了构建单元、表面相互作用和吉布斯自由能对组装过程的影响。我们系统地研究了引导晶面控制MOF组装的三种方法，包括自发组装、外力引导组装和通过表面改性进行组装。最后，我们展望了基于MOF材料制造的未来进展以及潜在应用探索。
