Title: Reverse Vesicles from a Salt-Free Catanionic Surfactant System: A Confocal Fluorescence Microscopy Study
Abstract: We give a detailed confocal fluorescence microscopy study on reverse from a salt-free catanionic surfactant system. When laurate (TTAL) and lauric acid (LA) are in cyclohexane at the presence of a small amount of water, stable vesicular phases form spontaneously. The reverse vesicular can be easily labeled with dyes of varying molecular size and while the dyes are nearly insoluble in cyclohexane reverse vesicles. This indicates the reverse vesicular phases be good candidates to host guest molecules. With the help of a microscope combined a confocal method, the features of interesting reverse supramolecular self-assemblies were revealed the first time. Because of the absence of electrostatic repulsions hydration forces between adjacent vesicles, the reverse vesicles a strong propensity to aggregate with each other and form clusters. The size distributions of both individual vesicles and clusters are polydisperse. Huge multilamellar vesicles with closely stacked thick walls (giant reverse onions) observed. Besides the spherical reverse vesicles and onions, other structures such as tubes have also been detected and evolutions between different structures were noticed. These supramolecular self-assemblies form in a nonpolar organic may serve as ideal micro- or nanoreaction centers for biological reactions and synthesis of inorganic nanomaterials.
