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 (ZrCl 4 ) 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 CO 2 uptake capacities and selectivities.
