Аннотация:C60(CF3)H, a readily preparable fullerene derivative with well-defined structure, reveals the properties of an electron-acceptor material with n-type conductivity and of a promising electrocatalyst for the oxygen reduction reactions (ORR). We present characterization and electrochemical studies of C60(CF3)H including testing of the prototypical P3HT/C60(CF3)H ORR photoelectrodes.
