Ionic liquids with acidic properties have been examined for use as solvents for biomaterials and as potential electrolytes for fuel cells. Recent work indicates that proteins and biopolymers such as silk and cellulose require hydrogen bonding for solvation in ionic liquids. In the present study, we have synthesized ionic liquids with imidazolium, guanidinium or ammonium cations containing acidic protons. These salts have simple anions such as Cl-, NO3-, HSO4-, and H2PO4-. We will discuss the characterization of the thermal and structural properties of these new ionic liquids using DSC, TGA, NMR, MS and Raman spectroscopy. In addition, we will present investigations of the relative acidities of these ionic liquids using spectroscopic probes.
