羧酸类金属有机框架材料的合成及应用

金属-有机框架材料(Metal-Organic?Frameworks，简称MOFs)是由金属离子（簇）与有机桥接配体通过配位共价键或弱相互作用自组装形成的一类具有分子内孔隙的有机-无机杂化材料。羧酸类MOFs材料中金属中心和有机羧酸配体的可变性导致了其结构和功能的多样性，在气体的吸附与分离、荧光、传感、药物传输以及电催化等多个领域展现了独特的应用前景，并被认为是当今科学上最有前途的材料之一。对于有机配体的选择，从早期易坍塌的含氮杂环类配体过渡到了如今稳定性好的羧酸类配体，解决了不少以前出现的MOFs材料结构单一易坍塌问题。

Synthesis and Application of Metal-Organic Framework Based on Carboxylate Ligands

Metal-organic frameworks are an organic-inorganic hybrid materials with intramolecular pores, which is composed of metal ions (clusters) and organic bridging ligands through coordination covalent self-assembly. The variability of metal centers and organic carboxylic acid ligands in MOFs leads to the diversity of their structure and function, which shows unique application prospects in many fields such as gas adsorption and separation, fluorescence, sensing, drug transport and electrocatalysis, and is considered as one of the most promising materials in science today. For the selection of organic ligands, from the early nitrogen-containing heterocyclic ligands that were prone to collapse to the current carboxylic acid ligands with good stability, it has solved the problem that many MOFs materials have single structure and prone to collapse.
