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 pillararene or crown ether, which decrease/or/increase the LCST by ~10°C, when present already below 100mM concentration.
