The highly fluorinated chiral [ital C][sub 3[ital h]] molecule C[sub 60]F[sub 48] was observed to sequentially attach two electrons in the gas phase to produce C[sub 60]F[sub 48][sup 2[minus]] and C[sub 60]F[sub 46][sup 2[minus]]+F[sub 2]. The first electron affinity (EA) of C[sub 60]F[sub 48] was measured to be 4.06[plus minus]0.3 eV. The first and second EA were calculated to be EA[sub 1]=5.07 eV and EA[sub 2]=2.27 eV for the more symmetric [ital D][sub 3[ital d]] isomer. The dianion was found to be [ital more] [ital stable] with respect to electron detachment than the singly-charged anion. This remarkable stability of the dianion is attributed to a potential barrier resulting from the long range Coulomb repulsion and short range electron-molecule binding. |
