Cationic surfactant self-assembly in choline chloride:malonic acid deep eutectic solvent

Abstract: Deep Eutectic Solvents (DES) are mixtures of organic salts and hydrogen bond donors, that form strongly hydrogen-bonded room temperature ionic liquids (ILs). DES share many features with ILs (ie. tunable physicochemical properties) which makes them viable green solvents that are less toxic than typical ILs. In our recent work we have studied amphiphile self-assembly in DES with the aim of developing templated deep eutectic-solvothermal syntheses. We found initially that the anionic surfactant SDS in a choline chloride-urea DES has an unusually inverted phase transition from cylindrical to spherical micelles as the surfactant concentration is increased. However, we recently found the same effect for the cationic surfactant CTAB in the DES choline chloride-malonic acid, which is an entirely different system. Here we would like to investigate this effect fully and determine its origin.
