Singular supramolecular self-assembling of bis-cyclodextrinyl-bis-lariat hosts with metal bis-aryl-sulfonates as guests

Résumé

The self-organization of bis-cyclodextrinyl-lariats (CD-L's) around divalent metal-sulfonates is described. Several new pseudo-rotaxanes were prepared by a template-directed approach involving bis-CD-L synthetic receptors and bis-sulfanilate or bis-tosylate metal salts as anion/cation guests. The non-covalent interactions between hosts and Zn-II, Cu-II, Ca-II bis-arylsulfonates guests were studied by 1D- and 2D-NMR confirming the formation of 1:1-complexes driven by a dual anion/cation recognition.
