Two zeolitic imidazolate frameworks, ZIF-67 and ZIF-8, were interrogated for their redox properties using Fourier transformed alternating current voltammetry, which revealed that the 2-methylimidazolate ligand is responsible for multiple redox transformations. Further insight was gained by employing discrete tetrahedral complexes, [M(DMIM)₄]²⁺ (DMIM = 1,2-dimethylimidazole, M = Co^II or Zn^II) which have similar structural motifs to ZIFs. In this work we demonstrate a multidirectional approach that enables the complex electrochemical behavior of ZIFs to be unraveled.

使用傅里叶变换交流伏安法在沸石咪唑酸酯骨架中解开复杂的氧化还原化学

使用傅立叶变换交流伏安法研究了两个沸石咪唑盐骨架ZIF-67和ZIF-8的氧化还原特性，结果表明2-甲基咪唑啉配体负责多次氧化还原。通过使用具有与ZIF相似的结构基序的离散四面体复合物[M（DMIM）₄ ] ²⁺（DMIM = 1,2-二甲基咪唑，M = Co ^II或Zn ^II）获得了进一步的见解。在这项工作中，我们展示了一种多向性方法，该方法可以揭示ZIF的复杂电化学行为。
