Does the influence of substituents impact upon the surface composition of pyrrolidinium-based ionic liquids? An angle resolved XPS study.
Physical Chemistry Chemical Physics
The surface chemistry of a series of four pyrrolidinium based ionic liquids, [C nC 1Pyrr][Tf 2N] where n = 4-10, is investigated by angle resolved X-ray photoelectron spectroscopy (ARXPS). The importance of sample purity is demonstrated and the stability of the ionic liquids under X-ray irradiation investigated. It is apparent that the surface chemistry and orientation is broadly analogous to that of similar imidazolium-based systems. © 2012 the Owner Societies.
