Abstract

We report the synthesis, characterization and physical properties of cyano and hydrocyano C60 derivatives. Electrochemical studies using differential pulse voltammetry (DPV) have shown that cyano groups on C60 increase the reduction potential and acidity of the proton on C60. It was shown that the reduction peak of C60(CN)4 is 280 mV more positive than the corresponding C60 peak. It was also found that C60H(CN)3 is highly acidic. This compound was estimated to be a stronger acid than dichloroacetic acid.
