Pyrazolino [60]fullerenes: synthesis and properties

We describe our contribution to the functionalization of fullerenes by 1,3-dipolar cycloaddition reactions in the preparation of pyrazolino [60]fullerenes. Several advantages that are inherent in the use of nitrile imines, with respect to other procedures for the derivatization of C60, will be discussed. Electrochemical and photochemical properties of this new family of fullerene derivatives suggest that they are good candidates for incorporation into new donor–acceptor assemblies.
