Design, synthesis, and applications of metal-organic frameworks (MOFs) are among the most salient fields of research in modern inorganic and materials chemistry. As the structure and physical properties of MOFs are mostly dependent on the organic linkers or ligands, the choice of ligand system is of utmost importance in the design of MOFs. One such crucial organic linker/ligand is terpyridine (tpy), which can adopt various coordination modes to generate an enormous number of metal-organic frameworks. These frameworks generally carry physicochemical characteristics induced by the π-electron-rich (basically N-electron-rich moiety) terpyridines. In this minireview, the construction of 3D MOFs associated with symmetrical terpyridines is discussed. These ligands can be easily derivatized at the lateral phenyl (4'-phenyl) position and incorporate additional organic functionalities. These functionalities lead to some different binding modes and form higher dimensional (3D) frameworks. Therefore, these 3D MOFs can carry multiple features along with the characteristics of terpyridines. Some properties of these MOFs, like photophysical, chemical selectivity, photocatalytic degradation, proton conductivity, and magnetism, etc. have also been discussed and correlated with their frameworks.
金属有机框架材料（MOFs）的设计、合成及应用是现代无机化学和材料化学中最突出的研究领域之一。由于MOFs的结构和物理性质主要取决于有机连接体或配体，因此在MOF的设计中，配体体系的选择至关重要。三联吡啶（tpy）就是这样一种关键的有机连接体/配体，它可以采用多种配位模式生成大量的金属有机框架材料。这些框架材料通常具有由富π电子（基本上是富N电子部分）的三联吡啶诱导产生的物理化学特性。在这篇综述中，我们讨论了与对称三联吡啶相关的三维MOFs的构建。这些配体可以很容易地在侧苯基（4'-苯基）位置进行衍生，并引入额外的有机官能团。这些官能团导致了一些不同的结合模式，并形成了更高维度（三维）的框架结构。因此，这些三维MOFs除了具有三联吡啶的特性外，还可以具有多种特征。本文还讨论了这些MOFs的一些性质，如光物理性质、化学选择性、光催化降解、质子传导性和磁性等，并将其与它们的框架结构进行了关联。
