It is known that lecithin can form self-assembled structures such as vesicles in aqueous solution. Compared to the self-assembly of lecithin in water, the reverse self-assembly of lecithin in organic solvents is much less known. In this study, we investigate a simple and reliable route to create the reverse self-assembled structures by mixtures of lecithin and chloride salts such as LiCl, CaCl2, and LaCl3 in cyclohexane. By controlling the concentration of salts, the transition of reverse self-assembled structures (reverse spherical, cylindrical micelles, and reverse vesicles) was observed. Diverse techniques such as dynamic light scattering (DLS), small-angle x-ray scattering (SAXS), and transmission electron microscope (TEM) were used to confirm the structures. |
