From LCST to crystals: structural modulation of ionic liquids drives the phase transition of poly(2-isopropyl-2-oxazoline)
Poly(2-isopropyl-2-oxazoline) (PiPrOx) exhibits UCST- or LCST-type phase transitions in ionic liquids (ILs) depending on the IL structure. In LCST-type ILs, where low solution entropy is favorable, PiPrOx crystallizes immediately after phase separation, unlike in water. FT-IR reveals a <i>trans</i>-rich conformation with structural constraint, facilitating both LCST-type phase separation and rapid crystallization.
