| New species of two categories of ionic liquids based on polyammonium cations have been prepared. These specifically are new polycationic liquid ionic phosphates (LIPs)and polyammonium ionic liquid sulfonamides (PILS). PILS bear the anion bis(trifluoromethylsulfonyl)imide while LIPs have simple phosphate as the counterion. These new species have been characterized by NMR and checked for residual halide content; in addition, Karl Fisher titration has been used to determine the residual water content of both types of species. Materials with less than 0.5 percent residual water were capable of being prepared with ease and were investigated further to determine their physical properties, including measurement of their specific conductivity. Both LIPs and PILS have also been investigated for their characteristics under pulse radiolysis using facilities at Brookhaven National Laboratory. |
