This proposal aims to explore aggregation behavior of common surfactants in magnetic ionic liquids (MILs) and to investigate the effect of a magnetic field on aggregate size, shape and orientation. Such systems are especially significant as until now, with the exception of photosurfactants [1], it has only been possible to affect such behaviour intrusively (e.g. altering pH or temperature). Now, by turning on or off a magnetic field it may be possible to reversibly control aggregation behaviour, by altering the structure of the underlying solvent medium. This has potential applications spanning emulsions, magnetophoresis and catalysis.
