Separation of substituted fullerenes using non-aqueous reversed-phase liquid chromatography-mass spectrometry.

A simple non-aqueous reversed-phase separation HPLC-MS method has been developed to allow for the rapid screening and separation of fullerenes and substituted fullerenes. This procedure provides confirmation that the proposed substitution methodology for the fullerene is not only successful but that multiple substitution products are obtained. The methodology is being expanded to analyze other substituted fullerene product mixtures.

Synthesis of a new ligand for transition metal-fullerene supramolecular systems.

A new ligand has been designed that provides a relatively simple framework to build supramolecular systems containing both fullerene and transition-metal moieties. The modular framework of the ligand allows for the easy design of more complex systems. Analysis of absorption and emission spectra suggests significant photoinduced charge transfer between the two moieties.
