Ionic liquids (ILs) have been described as designer solvents because they can be structurally manipulated to provide desired properties. This work focuses on the preparation of several series of ILs and an investigation of their physical and biological properties. Common cations such as imidazolium, pyridinium and pyrrolidinium with functionalized alkyl substituents and phosphate, bis(trifyl)imide or bis(oxalate)borate anions have been synthesized. Less common cations including 4-dimethylaminopyridine (DMAP), diazabicyclo[2.2.2]octane (DABCO) and diammonium species have also been similarly prepared. The physical properties of several of these ILs such as conductivity, viscosity and thermal profile will be reported. In addition the biological properties of the ILs have been evaluated through collaborative studies and will be briefly discussed. This work was supported in part at BNL by the U. S.
