| Abstract |
We report the strategies for the preparation of discrete metallosupramolecular cages using the multilevel coordination-driven assembly concept. A well-organized and higher-order molecular cage (CH3-Ni cage), [Ni8(PDA)6(MIP)3(DMF)6]6 . [Ni(H2O)3]4 (1) (PDA = 2,6-pyridinedicarboxylate, MIP = 5-methylisophthalic acid, DMF = dimethylformamide) can be regarded as the coordination-driven assembly of six methyl-functionalized nickel (Ni) triple-stranded helicates (CH3-Ni TSHs) as supramolecular modules and six-coordinate octahedral nickel ions. The replacement of 5-methylisophthalate with 5-tert-tbutylisophathalate leads to the formation ofan isomorphous molecular cage (tbu-Ni cage), [Ni8(PDA)6(tbu-PTA)3(DMF)6]6 . [Ni(H2O)3]4 (2) (tbu-PTA = 5-tert-tbutylisophathalate). Similar to 1, molecular cage 2 can be designated as the result of supramolecular assembly. The presence of well-defined and robust cavities of the synthesized cages renders them promising in selective gas sorption/separation application. |
