The mixed-ligand metal–organic framework (MOF) DMOF-1 has been successfully synthesized via ligand: 2,3,5,6-tetramethylterephthalic acid (TM), 9,10-anthracenedicarboxylic acid (ADC), 1,4-naphthalenedicarboxylic acid (NDC), 2,5-dimethyl terephthalic acid (DM), and metal (Zn, Cu, Ni, Co) substitutions to develop structure–property relationships for adsorption of water and SO2, an acid gas commonly found in flue gas streams at ppm-level concentrations. The substitution of bulky ligands, TM and ADC, resulted in not only improved water stability but also stability toward dry SO2, whereas substitution with NDC and DM did not provide water or SO2 stability. ADC-functionalized Zn–DMOF exhibited the greatest stability under humid SO2 exposure of the ligand-functionalized materials that were tested. Metal substitution of Cu into the DMOF–TM structure resulted in the greatest stability of the M–DMOF–TM samples upon exposure to humid SO2, and Ni–DMOF–TM provided the second most stable material. These results follow the prediction of the Irving–Williams series of metal node/ligand bond strengths.

DMOF-1作为潮湿和干燥条件下SO 2吸附的代表性MOF
通过配体成功合成了混合配体金属-有机骨架（MOF）DMOF-1：2,3,5,6-四甲基对苯二甲酸（TM），9,10-蒽二羧酸（ADC），1,4-萘二甲酸酸（NDC），2,5-二甲基对苯二甲酸（DM）和金属（Zn，Cu，Ni，Co）取代，从而开发出结构与性质的关系，以吸附水和SO 2（烟道气中常见的酸性气体）流的浓度为ppm级。庞大的配体TM和ADC的取代不仅改善了水的稳定性，而且提高了对干燥SO 2的稳定性，而用NDC和DM取代则不提供水或SO 2的稳定性。ADC功能化的Zn–DMOF在潮湿的SO 2下表现出最大的稳定性暴露测试的配体官能化材料。在暴露于潮湿的SO 2中，将铜金属置换为DMOF-TM结构导致M-DMOF-TM样品具有最大的稳定性，而Ni-DMOF-TM提供了第二稳定的材料。这些结果遵循了Irving–Williams系列金属节点/配体结合强度的预测。
