Zwitterionic imide compounds are provided according to the formula: R1-SO2-N--SO2-R2+, where R1 and R2+ are any suitable groups. Typically R1 is 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. |
