Watching phase transitions: Ordering processes and phase transitions in thin films of the liquid-crystalline ionic liquid 1,3-didodecylimidazolium tetrafluoroborate [C12C12IM][BF4] on Pt(111) (see picture) are studied by means of temperature-dependent IR reflection absorption spectroscopy. The method allows in situ monitoring of the structural properties of liquid-crystalline supported ionic liquid phase (SILP) catalysts under reaction conditions.
