Aryl- and alkyl-fullerenes or macromolecular fullerenes are often synthesized via the addition of carbon nucleophiles such as organolithium and Grignard compounds. Fullerenols contain many hydroxyl groups, which play an important role for the properties of fullerenols such as scavenging oxygen radicals, solubility, and other properties. However, those hydroxyl groups are also sensitive to organolithium and Grignard compounds. Therefore, for the synthesis of aryl- and alkyl-fullerenols, those hydroxyl groups must be protected before the formation of C-C bonds and to date no aryl-, alkyl-fullerenols or macromolecular fullerenols have been reported. Here we report an efficient one-pot synthesis of poly(diphenylmethylfullerenol) by the reaction of C60 with bromodiphenylmethane in basic aqueous solution. The approach not only provides the evidence for the existence of carbanions for the mechanism of nucleophilic addition of OH- to the double bonds of C60, but also provides an efficient, easy, one-pot synthetic approach for aryl- and alkyl-fullerenols. |
