摘要

Pulse radiolysis was applied to investigate the reaction of C_(60)(OH)_(36) with ~·OH radicals of hydrated electrons (e_(aq)~-). The second-order rate constants for the reactions between fullerenol and ~·OH radicals (2 × 10~9 dm~3 mol~(-1) s~(-1)) or hydrated electrons (2.5 × 10~9 dm~3 mol~(-1) s~(-1)) were determined. The most probable mechanism of the reaction of ~·OH with fullerenol was via the formation of a π-complex that could dissociate to reform the reactants in competition with the rearrangement to the σ-complex. The large number of hydroxyl groups attached to the fullerenol carbon cage did not result in any significant change in the rate constant for the reaction of fullerenol with hydroxyl radicals or e_(aq)~-.
