Diastereomeric cinchona based surfactants: features and chirality expression of their aggregates

The preparation and the aggregation properties of new diastereomeric cationic cinchona derivatized surfactants are described. The opposite configuration of a stereogenic center strongly influences the morphology, the colloidal features, and the chiral recognition capabilities of the diastereomeric aggregates that have been investigated by various physico-chemical tools.
