The efficient and selective capture of toxic oxo-anions is highly desirable for environmental retrieval and hazardous waste disposal. This has remained an important task and gained considerable scientific attention due to their harmful effects on the ecosystem and human health. Herein, a porous cationic metal-organic framework (MOF), namely, [CuCl(L)(HO)]·Cl·4DMA·8HO (1), was synthesized (HL = 1,4,8,11-tetrazacyclotetradecane-N,N',N'',N'''-tetramethylenecinnamic acid and DMA = N,N'-dimethylacetamide). 1 shows high stability in aqueous solution and represents an extraordinary example that is capable of efficiently capturing environmentally toxic CrO and MnO anions. Moreover, the removal of CrO and MnO anions from water was also explored in the presence of other competing anions.
高效且选择性地捕获有毒的氧阴离子对于环境修复和危险废物处理非常重要。由于它们对生态系统和人类健康的有害影响，这仍然是一项重要的任务，引起了相当多的科学关注。在此，合成了一种多孔阳离子金属有机骨架（MOF），即 [CuCl(L)(HO)]·Cl·4DMA·8H 2 O（1）（HL = 1,4,8,11-四氮杂环十四烷-N,N',N'',N'''-四亚甲基丙二酸和 DMA = N,N'-二甲基乙酰胺）。1 在水溶液中表现出高稳定性，是一个能够高效捕获环境有毒 CrO 和 MnO 阴离子的杰出例子。此外，还研究了在存在其他竞争阴离子的情况下，从水中去除 CrO 和 MnO 阴离子的情况。
