Comportement éléctrochimique du C60 et du C70 en milieu aqueux

The electrochemical behavior of C60 and C70 has been investigated either in organic media or in water, using notably platinium ultramicroelectrode as the working electrode. The differences between the redox potentials of C60 relative to C70 indicate that it is easier to add electrons to C70 and its anions compared to the counterparts of C60. In the second part of the work, the solubilisation of C60 has been achieved using cyclodextrine or triton X-100. The determination of the amount of C60 per micelle was investigated using UV-Visible spectroscopy.
