Novel fulleropyrrolidinium-based materials

The cyclic voltammetry of a series of soluble N-methylfulleropyrrolidinium salts shows that these materials are better electron-acceptors than unmodif ied C-60. The stability of mono-reduced, zwitterionic, and doubly-reduced a nionic species, produced either electrochemically or chemically, has been c hecked by absorption spectroscopy. Langmuir-Blodgett (LB) layers of the C-6 0 derivatives mixed with tricosanoic acid have been built up on different s ubstrates. The optical properties of the films have been characterized usin g absorption spectroscopy and their structure was investigated by X-ray dif fraction.
