Abstract

The DNA cleavage via superoxide anion, formed in photoinduced electron transfer from NADH to γ-cyclodextrin-bicapped C60 in a oxygen-saturated aqueous solution, was discussed. The reorganization energy for the reduction of O2 to O2.- was found to be 43.4 Kcal mol-1. The analysis suggested that the electron transfer from C60.-/γ-CyD to O2 proceeded via an outer sphere pathway.
