In the process of designing new MOFs with the aim of having a specific morphology, the shape of the linkers and the choice of coordinating metals have major importance. In this study, the aim to create novel hnb non-interpenetrating MOFs led us to choose tritopic linkers. Novel star-shaped molecules, presenting trigonal geometry and based on aromatic rings, were synthesized. For more convenient synthesis of the library, C–C coupling reactions via a direct arylation methodology were performed. This new synthetic tool, together with the idea of a molecule as a modular combination of smaller building blocks, made possible the fast, cheap and reproducible production of this class of compounds and also its scale-up. With one of the compounds, a MOF was synthesized and characterised via its specific surface area, which varies between 1681 and 3770 m² g⁻¹.

用于介孔 MOFs 的星形有机连接体的战略设计与合成

在设计具有特定形态的新 MOF 的过程中，连接体的形状和配位金属的选择非常重要。在这项研究中，为了创造新的hnb非互穿 MOF，我们选择了三主题链接器。合成了具有三角形几何形状并基于芳香环的新型星形分子。为了更方便地合成文库，通过直接芳基化方法进行C-C 偶联反应。这种新的合成工具，再加上将分子作为较小构建块的模块化组合的想法，使得这类化合物的快速、廉价和可重复的生产及其规模化成为可能。使用其中一种化合物，合成并表征了 MOF通过其比表面积，该比表面积在 1681 和 3770 m ² g ^-1之间变化。
