Syntheses,Crystal Structures And Properties Of Inorganic-organic Hybrid Complexes Based On Resorcin [4] Arene And POMs

Twonewinorganic-organichybridcomplexes,namely,{[Co₄L₂（HCOO）₂（OH）₂][SiO₄（W₃O₉）₄]}·6DMF·5H₂O（1）and{[Zn₄L₂（HCOO）₂（OH）₂][SiO₄（W₃O₉）₄]}·6DMF·5H₂O（2）have been solvothermally prepared by assembly of a new methyl imidazole functionalized resorcin[4]arene（L）,polyoxoanion（POM）and metal cation.Isostructural 1 and 2 feature porous supramolecular architectures and represent an unusual example of successful combination of resorcin[4]arenes with POMs.The complexes have been characterized by X-ray single crystal diffraction,elemental analysis,IR,thermogravimetric and PXRD.Remarkably,selective adsorptions for organic dyes were studied by using 1 and 2 as recycled adsorbents.Moreover,their electrocatalytic activities for the reduction of BrO₃^-and oxidation of ascorbic acid（AA）were also investigated.
