Electrochemical and photochemical processes of a singly bonded C 60 dimer (RC60-C60R), where R is diethoxyphosphorylmethyl (-CH2P(=O)(OEt)2), have been investigated using laser flash photolysis methods. Chemical reduction of RC 60-C60R generated the anion of dissociated fullerene (RC60- ) as a final reduction product, which is in agreement with irreversible cyclic voltammogram. Photoinduced one-electron reduction of RC60-C60R in the presence of N,N,N′,N′-tetramethyl-1,4-phenylenediamine via the triplet excited state of RC60-C60R generated initially the delocalized radical anion of RC60-C60R [(RC60-C 60R).-], which transformed into the localized radical anion [(RC60).--C60R] which showed a similar transient absorption spectrum to that of the radical anion of R 2C60. Photoexcitation of RC60-C60R in the absence of electron donor yields free radical (RC60.) via the excited state of RC60-C60R. Interactions between two RC60 moieties in the ground and excited states of RC 60-C60R have also been discussed.
