Multicomponent metal‐organic frameworks (MOFs) are built up from multiple ligands that are geometrically distinct. These ligands occupy specific positions in the MOF lattice. Installing different functionalities at precise locations in the framework is an important step in making MOFs for specific applications. This can be achieved by designing functionalized ligands for multicomponent MOFs. Here, we report a simple synthetic procedure for a new tritopic triazatruxene based tricarboxylic acid, H₃tat. We show that this ligand can be symmetrically derivatized with various substituents on its nitrogen centres. We report a new isoreticular series of well‐ordered quaternary MOFs based on these new triazatruxene ligands together with two linear carboxylate ligands and Zn₄O clusters. These MOFs are isostructural to the previously reported MUF‐77 series and show similar high surface areas and large pore volumes. Furthermore, H‐bonding between the NH sites of the incorporated triazatruxene ligands and guest molecules is employed to modify their fluorescence behavior.

用于多组分金属有机骨架的Tritopic三氮杂卓烯配体

多组分金属有机骨架（MOF）由几何上不同的多个配体组成。这些配体在MOF晶格中占据特定位置。在框架中的精确位置安装不同的功能是为特定应用制作MOF的重要一步。这可以通过设计用于多组分MOF的功能化配体来实现。在这里，我们报告了一个新的基于三氮杂三氮杂苯的三羧酸H ₃ tat的简单合成程序。我们表明，该配体可以在其氮中心被各种取代基对称衍生。我们报告了一个基于这些新的三氮杂卓烯配体以及两个线性羧酸酯配体和Zn _4的新的等序四级MOF的等网状系列O簇。这些MOF与先前报道的MUF-77系列具有同构结构，并显示出相似的高表面积和大孔体积。此外，掺入的三氮杂卓烯配体的NH位与客体分子之间的氢键可用于修饰其荧光行为。
