A stable microporous anionic metal-organic framework (MOF), [(CH)NH][CdL(HO)]·12HO (1), has been synthesized via solvothermal assembly of a new resorcin[4]arene-functionalized dodecacarboxylic acid (HL) and Cd(II) cations. The constructed MOF (1) was characterized by single-crystal X-ray diffraction and other physicochemical analyses. 1 exhibits a fascinating 3D microporous framework structure, in which the free water molecules and the [(CH)NH] cations were located. Remarkably, the exposed Lewis acid Cd(II) sites of activated 1 make it an efficient heterogeneous catalyst for the cycloaddition of CO with epoxides at 1 and 20 atm. Importantly, the activated samples of 1 can be reused at least five circles with excellent catalytic performance. Moreover, the fluorescence detection of CrO and Fe was studied by using 1 as a potential luminescent sensor.
通过新的均苯[4]芳烃功能化的十二羧酸（HL）和 Cd(II)阳离子的溶剂热组装，合成了一种稳定的微孔阴离子金属有机骨架（MOF），[(CH)NH][CdL(HO)]·12HO（1）。通过单晶 X 射线衍射和其他物理化学分析对构建的 MOF（1）进行了表征。1 呈现出迷人的 3D 微孔骨架结构，其中包含游离水分子和[(CH)NH]阳离子。值得注意的是，活化 1 的暴露的路易斯酸 Cd(II)位点使其成为 CO 与环氧化物在 1 和 20 大气压下环加成的高效非均相催化剂。重要的是，1 的活化样品可以至少重复使用五圈，具有出色的催化性能。此外，还研究了 1 作为潜在发光传感器对 CrO 和 Fe 的荧光检测。
