We now report the first cyclic voltammetric study of C[sub 60]F[sub 48] and the characterization of the products formed in the successive addition of electrons to C[sub 60]F[sub 48] in solution by various electron donors using electrospray mass spectrometry (ES-MS). Cyclic voltammograms (CVs) of C[sub 60]F[sub 48] was performed in a CH[sub 2]Cl[sub 2] solution. The reduction of C[sub 60]F[sub 48] to its anion radical occurs at E[sub 1/2]=-0.43 V with respect to the 9,10-diphenylanthracene (DPA)/9,10-diphenylanthracene radical cation (DPA[sup [sm bullet]+]) reference redox couple used in this experiment, or 0.79 V with respect to the SCE. The peak current ratio, i[sub pa]/i[sub pc], of 0.98 and the peak separation, [Delta]E[sub p], of 66 mV ([Delta]E[sub p] of the DPA/DPA[sup [sm bullet]+], a reversible couple, is 80 mV)indicated that C[sub 60]F[sub 48] undergoes a reversible reduction to form C[sub 60]F[sub 48][sup [sm bullet][minus]]. The reduction potential of C[sub 60]F[sub 48] is 1.38 V more positive than that of the first reduction wave of C[sub 60], indicating that C[sub 60]F[sub 48] is much easier to reduce than C[sub 60]. Moreover, this potential is also more positive than that of most other neutral organic electron acceptors known to the authors. 22 refs., 2 figs.
