Abstract

Abstract A metal(II) ion (Cu2+)-induced vesicle phase was prepared from a mixture of n-undecylamine and CuCl2 in aqueous solution. Cu2+-ligand coordination with n-undecylamine results in the formation of molecular bilayers because Cu2+ can firmly bind to the amine groups of n-undecylamine which reduced the area of the head-group. In this system, no counterions in aqueous solution exist because of the Cu2+-ligand coordination, and the bilayer membranes are not shielded by salts. The vesicles were determined by transmission electron microscopy (TEM) images and dynamic light scattering (DLS) measurements.
