The bis-cyclopropanation of fullerene with tether-linked bis-malonates was used to synthesize fullerene bis-adducts having a π-electron rich aromatic ring as a donor in a face-to-face arrangement. The reactions of 2b-e with fullerene were performed in the presence of 1,8-diazabicyclo[5,4,0]undec-7-ene (DBU) and iodine. Results showed that a photoinduced intramolecular electron transfer caused quenching of its fluorescence in a polar solvent.
