A library of 20 UiO-66-derived metal-organic frameworks (MOFs) is synthesized in a combinatorial approach involving mixed ligand copolymerization and two post-synthetic modifications (PSMs) in tandem. Mixed ligand co-polymerization of benzene-1,4-dicarboxylic acid (BDC) and sodium 2-sulfoterephthalate (SS-BDC) with zirconium tetrachloride (ZrCl4 ) was used to prepare 5 groups of MOFs with the same UiO-66 topology but differing amounts of sulfate groups. These MOFs exhibit excellent water stabilities in a pH range of 1 to 12, together with high CO2 uptake capacities and selectivities.
通过一种组合方法合成了一个包含20种UiO-66衍生金属有机框架（MOF）的库，该方法涉及混合配体共聚和两个串联的后合成修饰（PSM）。使用对苯二甲酸（BDC）和2-磺基对苯二甲酸钠（SS-BDC）与四氯化锆（ZrCl4）进行混合配体共聚，制备了5组具有相同UiO-66拓扑结构但硫酸根含量不同的MOF。这些MOF在1至12的pH范围内表现出优异的水稳定性，同时具有高二氧化碳吸收能力和选择性。
