The UV-vis absorption spectra of chlorinated fullerenes (C{sub 60}Cl{sub 6}, C{sub 60}Cl{sub 12}) in cyclohexane exhibit bands with {lambda}{sub max} = 210 and 255 and shoulders at 275 and 385 nm. The sharpness and molar absorptivity decrease with increase in the number of chlorine atoms. Pulse radiolysis studies of these chlorinated fullerenes were carried out in benzene, 1,2-dichloroethane, and cycolohexane. In benzene, the triplets of chlorinated fullerenes were observed. The radical cations of chlorinated fullerenes, generated in 1,2-dichloroethane, exhibit absorption bands with {lambda}{sub max} = 400 nm for C{sub 60}Cl{sub 12} and 380 nm for C{sub 60}Cl{sub 6}. In cyclohexane, a slow forming transient at {lambda}{sub max} = 430 nm for C{sub 60}Cl{sub 12} and 370 nm for C{sub 60}Cl{sub 6} was generated. These bands appear to be different from the triplet and parent radical cation. 30 refs., 7 figs., 2 tabs.
