Stabilization and immobilization of polyoxometalates in porous coordination polymers through host–guest interactions

Construction of molecular rectangles with titanium–oxo clusters and rigid aromatic carboxylate ligands

“…Regular-shape coordination complexes are an important class of advanced molecular materials because of their numerous and diverse applications in probes, 1 host-guest chemistry, 2 catalysis, 3,4 molecular devices, 5,6 and photocatalysis. 7 The fabrication of various nanoscale molecular architectures such as triangles, squares, pentagons, hexagons, cages, and boxes has been well reported so far.…”

Crystal structure of catenapoly[diaqua-(μ 24,4′-bipyridine)-κ 2 N:N′)-bis(2,6-difluorobenzoate)-κO)nickel(II)] ethanol monosolvate, C28H30F4N2O8Ni

“…The penta uorobenzoate as ligand has been reported in some studies, while only few complexes with 2,6-di uorobenzoate (dfba) have been reported [7][8][9][10][11][12]. Meanwhile, 4,4′-bipyridine (bpy) is a common N-donor ligand, which has been widely used as bridging ligand to construct diverse structural networks [13][14][15][16]. In this paper, we report the synthesis, crystal structure of…”

Hybrid Organic-Inorganic Materials Based on Polyoxometalates and Ionic Liquids and Their Application in Catalysis

“…Another type of stabilization and immobilization of organic compounds through host-guest interactions was recently summarized in an extensive review [62]. Concerning the hybrids, Poli et al [63] presented a very complete and interesting study on the peroxotungstate catalyst immobilization on amphiphilic resin by ion exchange using the methylimidazole and imidazole based ionic liquids with different alkyl substitutes (from C 6 to C 12 ) as linkers.…”
