Dynamic Supra-MOF self-assembly of ZIF-7

Supra-MOF assemblies are the assemblies within the assembly. Metal-organic frameworks are nothing but the molecular self-assemblies of metal cations and organic linker anions, which may transition via the initial weak interaction assembly. A part of the molecular self-assembly may further develop into the islands of polycrystalline MOF particles surrounded by weakly interacting assembly. This has been evident from the previous reports on the supra-MOFs. Here in this report, we represent the dynamics of supra-MOF assembly constituting Zn(II) and Benzimidazole (BIm) that eventually results into the crystalline ZIF-7 compound. Results obtained in this work manifests the potential synthetic strategy for generating functional materials serving applications from different realms.
