Crystal Engineering in Solid-State Metal Salt Complexes of Cyclodextrins
Résumé
We have developed extensive investigations on the nature of the solid-state cyclodextrin-salt interaction and its effect on the molecular self-organization. The first examples of complexes were provided by β-cyclodextrin with metal chlorides1,2 (calcium and hydrated magnesium). Then, systematic crystallization experiments have been undertaken to determine the conditions for solidstate metal complexation, given the solubilities of α- β- and γ- cyclodextrins as a function of the salt concentration.
