Superoxide ion has been generated in ionic liquid trihexyl (tetradecyl) phosphonium bis (trifluoromethylsulfonyl) imide, [PI4, 666][N(Tf)2]. Cyclic voltammetry and chronoamperometry techniques were used for the electrochemical generation of 02'~, while chemical generation was done by adding K02 to DMSO. The long term stability of 02'~ was investigated using UV/Vis spectrophotometer. It was found that the quaternary phosphonium cation, [PI 4, 666]+ is a reasonably safe cation for the generation of 02'~ which indicates the possible use of ILs involving it for further useful applications.
