Electrochemical, ESR and theoretical studies of [6,6]-opened C60(CF2), cis-2-C60(CF2)2 and their anions

Abstract: Electrochemical behavior of C(60)(CF(2))(n), n = 1, 2 and C(60)(CCl(2)) has been investigated. [6,6]-Opened C(60)(CF(2)) and cis-2-C(60)(CF(2))(2) exhibit reversible reductions at potentials 150 and 145 mV more positive than C(60), unlike the related [6,6]-closed C(60)(CCl(2)), which shows reduction at the potential close to that for C(60). The structures, electron localization and lifetimes of the observed radical anions C(60)(CF(2))(-*) and cis-2-C(60)(CF(2))(2)(-*) have been elucidated by the ESR study and … Show more

“…With the decrease of the applied voltage, several less intensive peaks with a higher g-factor and smaller hfc values appear in the spectrum, more likely, owing to some side products involving the solvent (oDCB), as it has been reported earlier. [29] The g-value observed for C 60 (CF 2 )H 2 •-(2.0001 (2)), is smaller than that for C 60 (CF 2 ) •-(2.0017 (2)) [12] and is very close to the values measured for C 60 H 2 •-(2.000), [27] C 60 R 2…”

“…The peak-to-peak line width for the C 60 (CF 2 )H 2 •-(typically for doubly functionalized fullerenes [12,16,27,30,31] ) is significantly narrowed (0.7 G) as compared to the C 60 •-radical anion, in which small Jahn-Teller distortions and associated dynamic effects play a significant role. [27,32] Indeed, the DFT calculations of the C 60 (CF 2 ) •-and C 60 (CF 2 )H 2 •-radical anions show that the spin density at the 19 F nuclei is significantly higher than that at the protons (see Table 2).…”
