Metal–organic frameworks (MOFs) represent a sophisticated blend of inorganic and organic components, promoting the development of coordination chemistry greatly and offering a versatile platform for tailored functionalities. By combining various metal nodes, organic linkers, and functional guests, MOFs provide numerous pathways for their design, synthesis, and customization. Among these, sequential linker installation (SLI) stands out as a novel and crucial strategy, enabling the precise integration of desired properties and functions at the atomic scale. SLI enhances structural diversity and stability while facilitating the meticulous construction of robust frameworks by leveraging open metal sites and functional organic linkers at targeted locations. Compared to the direct synthesis of MOFs, postsynthetic modification methods allow for precise regulation of their structures and corresponding properties. While unlike conventional postsynthetic modification methods, SLI requires the careful selection of linkers and framework design to ensure precise positioning for installation, which gives rise to the well-designed and ordered positions for the installed linkers, confirmed directly by X-ray diffraction technology.

金属有机框架中的顺序连接器安装


金属有机框架 （MOF） 代表了无机和有机成分的复杂混合物，极大地促进了配位化学的发展，并为定制功能提供了多功能平台。通过结合各种金属节点、有机连接子和功能客体，MOF 为其设计、合成和定制提供了多种途径。其中，顺序连接器安装 （SLI） 是一种新颖且至关重要的策略，能够在原子尺度上精确集成所需的属性和功能。SLI 增强了结构多样性和稳定性，同时通过在目标位置利用开放金属位点和功能性有机连接剂来促进构建稳健的框架。与 MOF 的直接合成相比，合成后修饰方法可以精确调节其结构和相应的特性。虽然与传统的合成后改性方法不同，SLI 需要仔细选择连接子和框架设计，以确保安装的精确定位，这导致了安装连接子的精心设计和有序的位置，通过 X 射线衍射技术直接确认。
