Transition from Contact to Solvent-Separated Ion Pairs in protic ionic liquid/molecular liquid mixtures

Abstract: Among the most important features affecting the behaviour of Ionic Liquids (IL) and their mixtures with molecular liquids (ML), ion pairing is attracting a great attention. This is the outcome of a delicate balance between ion-solvent and cation-anion interactions and in protic ILs (PILs) these involve not only coulombic and dispersive interactions, but also hydrogen bonding ones. Recently reports describing the transition from Contact Ion Pairs to solvent separated ones in PILs mixed with ML with different polarity have appeared. When MLs with high enough polarity are mixed with PILs, indirect spectroscopic evidences of this transition have been observed. So far no direct structural evidence of such a transition (and of its absence when considering less polar MLs) has been provided. With this proposal, we ask for SANDALS beam time to explore such an issue on different PIL/MLs
