Resumen en inglés

Short helical amphipathic oligourea foldamers were designed with distinct hydrophobic and hydrophilic faces. Two of the foldamers (H2OC1 and H2OC2) obtained by solid phase synthesis self-assembled into channel-type nanostructures that show efficient water permeability across lipid membranes while rejecting ions. A self-assembled quaternary structure with two superhelical scaffolds results in the formation of 4.8 and 6.4 A ˚inner pores that were observed in the crystal packing of H2OC1. Both pores have hydrophilic interior and hydrophobic exterior surfaces. Our findings demonstrate the channel-forming ability of oligourea foldamers in lipid bilayers, and such novel artificial water channels could be beneficial for water purification applications.< Leer menos
