Back Cover: Water Structure Recovery in Chaotropic Anion Recognition: High‐Affinity Binding of Dodecaborate Clusters to γ‐Cyclodextrin (Angew. Chem. Int. Ed. 23/2015)

Abstract

A supramolecular anchor motif has been found that consists of dodecaborate dianions (B12X122−, X=H, Cl, Br, I) as purely inorganic guests and γ‐cyclodextrin as a macrocyclic host. As shown by K. Rissanen, D. Gabel, W. M. Nau et al. in their Communication on the high micromolar affinity of this hybrid organic–inorganic host–guest complex is traced back to the chaotropic (water structure‐breaking) nature of the globular clusters, their shape complementarity, and their high polarizabilities.
