RESUMEN

Hexakis(3,6-anhydro)tetrakis(2A,B,D,E-O-octyl) cyclomatohexaose (OCT) has been recently shown as a powerful cryptant for lead, mercury, and especially for uranyl. As previous results have been obtained in an organic solvent (methanol), a similar evaluation of OCT complex formation was achieved in aqueous medium and in the presence of membrane-mimicking systems such as phospholipid vesicles, liposomes and micelles. It was found that OCT, while completely insoluble in water, forms solid gel structures when in equimolar mixtures of water and methanol. Moreover, OCT exhibits detergent properties. Finally, OCT was successfully introduced in detergent solutions while keeping. Uranyl complexing properties. Possible applications of such models were also discussed.
