Abstract

Superoxide ion has been generated in room temperature ionic liquid trihexyl (tetradecyl) phosphonium bis (trifluoromethylsulfonyl)imide, [P14,666][N(Tf)₂]. Cyclic voltammetry and chronoamperometry techniques were used for the electrochemical generation of O^m₂^._, while chemical generation was done by adding KO₂ to dimethylsulphoxide (DMSO). The long term stability of O₂^._ was investigated using UV/Vis spectrophotometer. It was found that the quaternary phosphonium cation, [PI 4,666]⁺ is a reasonably stable cation in the presence of 0₂^._ which indicates the possible use of these ILs for further useful applications.
