| Abstract: | An effective method was developed for the synthesis of three cluster‐based frameworks with multifarious secondary building units (SBUs) and various structures, which were formulated as [Me2NH2]2[Zn10(BTC)6(μ3‐O)(μ4‐O)(H2O)5] · 3DMA · 9H2O ( FJI ‐ 3 ), [Me2NH2]2[Zn9(μ3‐OH)2(BTC)6(H2O)3] · 5DMA · 6H2O ( FJI ‐ 4 ) and [Me2NH2][Zn3(μ3‐OH)(BTC)2DMF] · H2O ( FJI ‐ 5 ) (H3BTC = 1,3,5‐benzenetricarboxylic acid, DMA = N,N′‐dimethyl acetamide and DMF = N,N′‐dimethyl formamide), respectively. X‐ray structural analysis reveals that FJI ‐ 3 displays 3D highly porous metal‐organic framework with four kinds of microporous cages constructed by two paddle‐wheel Zn2(CO2)4, trimeric Zn3O(CO2)6, and tetrameric Zn4O(CO2)6 SBUs. FJI ‐ 4 exhibits 3D microporous MOFs with a dodecahedral cavities built by paddle‐wheel Zn2(CO2)4 and trimeric Zn3O(CO2)6. FJI ‐ 5 shows 3D microporous MOFs with an 1D channel assembled by the Zn3O(CO2)6 SBUs. In addition, the fluorescence and sorption properties in these cluster‐based frameworks were also investigated. Furthermore, the method employed in this work may provide an useful approach to the design and synthesis of novel cluster‐based frameworks. |
