Abstract

Two polyoxometalate-templated organic-inorganic hybrid porous frameworks, namely, [Cu-2(H2O)(2)(bpp)(2)Cl][PM12O40]. similar to 20H(2)O (for 1, M = W; for 2, M = Mo; bpp = 1,3-bis(4-pyridyl)propane), were self-assembly obtained and structurally determined by elemental analyses, inductively coupled plasma analyses, infrared spectroscopy, and single-crystal X-ray diffraction analyses. Single-crystal X-ray analysis of these crystals revealed that both of the structures are constructed from eight-connected three-dimensional coordination polymer hosts [Cu-2(H2O)(2)(bpp)(2)Cl](n)(3n+) wand ball-shaped Keggin-type guests [PM12O40](n)(3n-) as templates. The polymer hosts resulted from a bcc-type framework with nanotubes, and the nanotubes can be regarded as a tetra-stranded helix structure. Furthermore, compounds 1 and 2 exhibit photoluminescent properties at ambient temperature, and the compound 2 bulk-modified carbon paste electrode (2-CPE) displays good electrocatalytic activity toward the reduction of nitrite.
