Ionic liquids based on imidazolium and pyrrolidinium salts of the tricyanomethanide anion

A novel series of tricyanomethanide ionic liquids have been prepared and characterized for potential use as ionic liquid solvents. Full thermal analyses of all salts at ambient and sub-ambient temperatures are reported (melting points-17degrees to 160degreesC). The thermal stability and decomposition temperatures are also presented (T-decomp approximate to 300degreesC). An electrochemical window of similar to3V has been established and the conductivity measured over a range of temperatures (20 mS cm(-1) at 25degreesC).
