F. Paolucci et al., Electrochemical detection of C-60 in solution - Is tetrahydrofuran a suitable solvent for fullerene studies?, J ELCHEM SO, 146(9), 1999, pp. 3357-3360
The electrochemistry of C-60 in tetrahydrofuran/tetrabutylammonium hexafluo
rophosphate (THF/TBAH) solutions was thoroughly investigated, and particula
r attention was devoted to possible interactions occurring between the full
erene and this medium and leading to irreversible modification of C-60 itse
lf. Either untreated or carefully purified solvent was used in the experime
nts, showing that only in the latter case can reliable results be obtained,
the occurrence of irreversible reactions between C-60 and an impurity pres
ent in traces (probably peroxides) having been monitored by both cyclic vol
tammetry (CV) and absorption spectroscopy. (C) 1999 The Electrochemical Soc
