A series of triad pyrazolylpyrazolinofullerenes has been prepared in one pot from suitably functionalized hydrazones by 1,3-dipolar cycloaddition reactions under microwave irradiation. The electrochemical properties of the compounds obtained were investigated by cyclic voltammmetry, and they show better electron acceptor character than the parent C60 in all cases. Fluorescence experiments and time-resolved transition spectroscopy indicate the existence of photoinduced chargetransfer processes with the C60 triplet acting as the acceptor.
