Abstract / Bemerkung
In this study the existence of the C-60 cation produced by photochemically induced electron transfer in the presence of different sensitising molecules is proved for the first time by using ESR spectroscopy. It is demonstrated for triphenylpyryliumtetrafluoroborate (TPP) by this spectroscopic method that the electron transfer from C-60 to TPP occurs without, an application of a cosensitiser. Furthermore it is shown that the addition of alcohols causes a new radical in the system C-60/TPP. The stationary concentration of the C-60 cation diminishes even in the presence of a cosensitiser to such a low concentration that it is not detectable by ESR spectrosopy. The spectroscopic study of the sensitiser/C-60 system is also extended to the reaction products.
