Secondary building units (SBUs) are the key components of metal–organic frameworks (MOFs) that help to build potentially porous periodic networks by linking multitopic organic ligands. Hence, metal SBUs are critical for determining the underlying topology of MOFs. Moreover, SBUs are the main MOF research topic nowadays, because of the simplicity of their synthesis, diverse directionality and their ability to easily harness open metal sites, compared to that of primary building units (comprising mononuclear metal centres) or tertiary building units (metal–organic polyhedra). Therefore, post-synthetic approaches for altering SBUs do not only include developing techniques for controlling the properties of MOFs but also involve a more in-depth understanding of their structure–function relationships from the materials science and engineering perspective. The SBU-related reviews published to date have successfully introduced and organised the chemistry of SBUs in MOFs. Because many recent studies have explored more diverse methods, such as metal exchange, oxidation-state transformation, defect generation, and incorporation of other species, in this review, we mainly focus on the recently developed methods for SBU alteration by classifying them into four groups and elaborate on how unique structures and properties can be achieved using those methods.

金属有机框架二级建筑单元的变更，以开发新功能

二级建筑单元（SBU）是金属有机框架（MOF）的关键组成部分，可通过连接多主题有机配体来帮助构建潜在的多孔周期网络。因此，金属SBU对于确定MOF的基础拓扑至关重要。此外，与主要建筑单元（包括单核金属中心）或第三建筑单元（金属）相比，SBU是当今MOF的主要研究主题，因为它们的合成简单，方向性多样且能够轻松利用开放金属场所。 –有机多面体）。所以，合成SBU的后合成方法不仅包括开发用于控制MOF特性的技术，而且还涉及从材料科学和工程学角度更深入地了解其结构-功能关系。迄今为止，与SBU相关的评论已成功引入并组织了MOF中SBU的化学结构。由于最近的许多研究都探索了更多样化的方法，例如金属交换，氧化态转变，缺陷生成和其他物种的掺入，因此在本综述中，我们主要将最近开发的SBU改变方法归类为四类。并详细说明如何使用这些方法实现独特的结构和属性。迄今为止，与SBU相关的评论已成功引入并组织了MOF中SBU的化学结构。由于最近的许多研究都探索了更多种多样的方法，例如金属交换，氧化态转化，缺陷生成和其他物种的掺入，因此在本综述中，我们主要将最近开发的SBU改变方法归类为四类。并详细说明如何使用这些方法实现独特的结构和属性。迄今为止，与SBU相关的评论已成功引入并组织了MOF中SBU的化学结构。由于最近的许多研究都探索了更多样化的方法，例如金属交换，氧化态转变，缺陷生成和其他物种的掺入，因此在本综述中，我们主要将最近开发的SBU改变方法归类为四类。并详细说明如何使用这些方法实现独特的结构和属性。
