"There is a considerable recent interest in the applications of room temperature ionic liquids (RTILs) as green solvents in organic synthesis and as nonvolatile electrolytes in lithium ion batteries. A variety of commercially available imidazolium based RTILs have been used for these applications, mainly due to their negligible vapor pressures, high thermal stabilities, wide liquid range, wide electrochemical windows and high anodic stability. The state of the art lithium ion batteries require the use of electrolytes that have relatively low viscosities at temperatures as low as -35°C. This thesis describes the synthesis of novel oxygenated and fluorinated imidazolium based RTILs that maintain liquid range at as low as -35°C, and their toxicity studies. The toxicities have been also measured as a function of counter-anions using human bronchoalveolar carcinoma cell line (A549), and determined their EC50 values. The toxicities of these newly synthesized ionic liquids are comparable to those of related imidazolium based RTILs, with concentration ranging from 0.2mM to 2.5 mM"--Abstract page iii.
