A series of novel soluble [60]fulleropyrrolidine derivatives bearing relatively simple substituents like [6,6]-phenyl-C sub(61)-butyric acid methyl ester (PC sub(61)BM) is synthesized under Prato reaction conditions. The photoabsorption and electrochemical properties of the fulleropyrrolidines are i...
