Micellization in alkyltriphenylphosphonium bromide:glycerol deep eutectic solvents.
Deep Eutectic Solvents (DES) are molecular mixtures similar to ionic liquids, having melting points below room temperature. However instead of being a salt, the mixture contains two molecules with strong H-bonding that hinder formation of an ordered crystalline network. DES share many features of ionic liquids (low vapour pressure, adjustable polarity, etc) which make them interesting as green solvents while being far less toxic than typical ionic liquids. We have begun to study the formation of surfactant micelles in these novel, tailorable solvents, and discovered distinct differences in micelle shape and evolution with concentration compared to aqueous solutions. Here we wish to continue these studies by changing the cation component of the solvent and studying micelles formed with cationic and anionic surfactants. These results will be compared to our current results on the same surfactants for DES where the H-bond donor was altered. We aim to build up a systematic description of micellization in these non-aqueous solvents to promote their use in new amphiphile based applications such as templating and emulsification.
