Abstract

Abstract : In this study, amphiphiles composed of linear polyglycerols (LPGs) with hydroxyl, methoxy, and ethoxy side groups and end capped with one or two perfluorooctyl chains (Rf8 ) have been designed to form supramolecular architectures. Abstract : In this study, amphiphiles composed of linear polyglycerols (LPGs) with hydroxyl, methoxy, and ethoxy side groups and end capped with one or two perfluorooctyl chains (Rf8 ) have been designed to form supramolecular architectures. The amphiphiles and bolaamphiphiles are capable of self-assembling into spherical and flat micelles as well as nonionic unilamellar vesicles (niosomes) in aqueous solution. The fluorous compartments of the micelles preferentially encapsulate a trifluoromethylated Disperse Red 1 compared to the unaltered dye. Micellar solutions of methoxy LPG compounds show a transition in water at temperatures of 38 °C (2 ) and 33 °C (5 ) in which reversibly larger agglomerates are formed. Both amphiphiles also form very stable unilamellar vesicles with diameters ranging from 30 nm up to 10 μm, if prepared via a thin film hydration method, which remain intact above 38 °C.
