ABSTRACT:
Zwitterionic imide compounds are provided according to the formula: R1—SO2—N−—SO2—R2+, where R1and R2+are any suitable groups. Typically R1is a highly fluorinated alkane and R2+contains a quaternary ammonium group or a heteroatomic aromatic group having an cationic nitrogen, such as: pyridiniumyl, pyridaziniumyl, pyrimidiniumyl, pyraziniumyl, imidazoliumyl, pyrazoliumyl, thiazoliumyl, oxazoliumyl, or triazoliumyl. Zwitterionic liquids are provided, typically having melting points of less than 100° C. and typically having a solubility in water of less than 5% by weight.
