英文摘要	the ionic liquid (il), tetrabutylphosphonium trifluoroacetate ([p-4444][cf3coo]) showed a low critical solution temperature (lcst)-type phase transition in water. it was found that [p-4444][cf3coo] molecules can form some kind of long-living aggregates in aqueous solution under certain conditions before the phase separation. these aggregates displayed the characteristic properties of microemulsions, although no surfactants are used. for instance, the aggregate droplet size can be adjusted by temperature and concentration, which behaves like the swelling phenomenon of microemulsions; the formed aggregates showed beneficial solubilization capacity for apolar substances; in addition, a tunable micropolarity in the aggregates is observed by the detection of uv-vis measurements. these are by far the simplest aggregates having the microemulsion characteristics. in nature, these microemulsion-like aggregates have mesoscopic phase separation, which is the intermediate state for macroscopic phase separation. this special system can be regarded as surfactant-free microemulsion-like aggregates and should be an effective platform to provide novel extraction or separation media.
