Abstract
The electrochemistry of in tetrahydrofuran/tetrabutylammonium hexafluorophosphate (THF/TBAH) solutions was thoroughly investigated, and particular attention was devoted to possible interactions occurring between the fullerene and this medium and leading to irreversible modification of itself. Either untreated or carefully purified solvent was used in the experiments, showing that only in the latter case can reliable results be obtained, the occurrence of irreversible reactions between and an impurity present in traces (probably peroxides) having been monitored by both cyclic voltammetry (CV) and absorption spectroscopy. © 1999 The Electrochemical Society.
