Aromaticity in anions in fluorine-free ionic liquids

Written by

ILs composed of bis(trifluoromethyl sulfonyl)imide (TFSI) anion with different nitrogen-based aromatic and aliphatic cations – such as imidazolium, pyridinium, pyrrolidinium, piperidinium and quaternary ammonium derivatives – are widely tested in energy storage research. The quaternary ammonium cations and their derivatives, coupled with the TFSI anion, have good electrochemical stability at room temperature, but are thermally less stable than their quaternary […]
