摘要
IR-visible sum frequency generation (SFG) vibrational spectroscopy was employed to investigate the microscopic structures at interfaces between room temperature ionic liquids and various molecular liquids. The alkyl chain of the [C(n)mim](+) polar cation orients toward the hydrophobic (CCl(4)) phase at the CCl(4)/ionic liquid interface, while it orients randomly or points towards the ionic liquid phase at a D(2)O/ionic liquid interface. An anomalous enhancement in the amplitude of the CD(3) asymmetric stretching mode is observed at a butanol/ionic liquid interface, suggesting the formation of a hydrophobic layer which consists of the alkyl chains of the butanol and the [C(n)mim](+) cation.
