A MIL-140D- framework has been used as a highly stable backbone for the introduction of 4,4'-azobenzene dicarboxylic acid (H ) solvent-assisted ligand exchange (SALE). The implemented azo groups can serve as coordination sites for copper ions. These can exchange ligands with different gases, but show a high selectivity against HS, which makes this material promising for potential sensor applications.
一种MIL-140D框架已被用作引入4,4'-偶氮苯二甲酸（H）的高度稳定骨架，通过溶剂辅助配体交换（SALE）实现。引入的偶氮基团可作为铜离子的配位位点。这些位点可以与不同气体进行配体交换，但对H₂S表现出高选择性，这使得这种材料在潜在传感器应用方面具有前景。
