Cyclic voltammograms are reported for C-60(CF3)(n) derivatives for the first time. The compounds studied were 1,9-C-60(CF3)(2) and 3 isomers of C-60(CF3)(10), including the structurally characterized derivative 1,3,7,10,14,17,23,28,31,40-C-60(CF3)(10) (C-60(CF3)(10)-3). The compound 1,9-C-60(CF3)(2) exhibited 3 reversible reductions; C-60(CF3)(10)-3(-) exhibited 2 reversible reductions; the other 2 isomers of C-60(CF3)(10) each exhibited 1 reversible reduction. ESR and near-IR spectroelectrochelnical experiments were performed to characterize some of the C-60(CF3)(n)(-) and C-60(CF3)(n)(2-) species generated by cyclic voltammetry. The ESR spectrum of the C-60(CF3)(10)3(-) radical anion consisted of an envelope of 25 lines centered at g = 2.0032 (the apparent a value is ca. 0.5 G), evidence of coupling between the unpaired electron and a significant number of the CF3 fluorine atoms. The most significant finding is that this radical anion has a half-life in solution at 25 degrees C of about 7 min.
