Thermodynamic data for caesium complexation with 18-crown-6 in various hydrophobic room-temperature ionic liquids were measured using (133)Cs NMR spectroscopy at 25 degrees C; the stability constants correlate well with crown ether assisted extraction degree of caesium from water into room temperature ionic liquids indicating an importance of complex stability for the extraction process.
