Lower critical solution temperature of an ionic liquid and its control by supramolecular host–guest interactions

The LCST is not restricted to macromolecular systems only, but can be found even in binary mixtures, although rarely. In this work our colleagues found and  ionic-liquid, which has LCST (~45°C) , when mixed with acetone. It was found, that LCST is not present in any of other 10  organic solvents tested, and also not when anion of ionic liquid is modified. Moreover the LCST is very sensitive to the addition of supramolecular hosts, such as pillar[5]arene or crown ether, which decrease/or/increase the LCST by ~10°C, when present already below 100mM concentration.
