Abstract

We report on spontaneous vesiculation of single-chain perfluorinated surfactant mixtures. The surfactants bearing oppositely charged headgroups form stable unilamellar vesicular aggregates upon gently mixing non-equimolar solutions. We have synthesized and employed a variety of perfluoro alkane single-chain surfactants (Figure 1). The obtained transparent solutions contained polydispersed aggregates. The unilamellar vesicles were characterized and investigated by quasi-elastic light-scattering, electronmicroscopy and nuclear magnetic resonance spectroscopy.
