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 Om 2 ._, 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.
