Our conceived approach based on the directed assembly of functional metal-organic squares (MOSs), 4-membered ring (4MR) building units, permitted the construction of two novel zeolite-like supramolecular assemblies (ZSAs), namely [Co (ImDC) (En) ]⋅9 H O⋅1.5 DMF (ZSA-10) and [Co (ImDC) (En) ]⋅7 H O (ZSA-11) (H ImDC=4,5-imidazoledicarboxylic acid, En=ethylenediamine, DMF=N,N-dimethylformamide). The elected MOSs encompass both trans- and cis-coordinated nodes, offering complementary peripheral functional groups for their directed assembly into zeolite-like topologies via supramolecular hydrogen bonding interactions. Distinctly, ZSA-10 possesses the underling MER zeolite topology and is the only pure MER framework material (without any supporting templates) exhibiting permanent porosity up to now. ZSA-11 has the underlying ABW topology together with one type of narrow channel.
我们基于功能性金属有机方块（MOSs）（四元环（4MR）构建单元）的定向组装所设想的方法，使得构建出两种新型类沸石超分子组装体（ZSAs）成为可能，即[Co(ImDC)(En)]⋅9 H₂O⋅1.5 DMF（ZSA - 10）和[Co(ImDC)(En)]⋅7 H₂O（ZSA - 11）（H₂ImDC = 4,5 - 咪唑二甲酸，En = 乙二胺，DMF = N,N - 二甲基甲酰胺）。所选的MOSs包含反式和顺式配位节点，通过超分子氢键相互作用为它们定向组装成类沸石拓扑结构提供互补的外围官能团。值得注意的是，ZSA - 10具有基础的MER沸石拓扑结构，并且是目前唯一一种表现出高达永久孔隙率的纯MER骨架材料（没有任何支撑模板）。ZSA - 11具有基础的ABW拓扑结构以及一种窄通道。
