Effect of Water and Solvent Selection on the SAFA Purification Times for Metallic Nitride Fullerenes

摘要

This paper addresses two key parameters in the SAFA purification method for isolating endohedral metallofullerenes. The percent water content in the reactive aminosilica significantly affects the time needed to isolate Sc3N@Ih-C80 metallic nitride fullerene (MNF). The role of solvent selection in the SAFA process is also discussed. The SAFA purification time needed for isolating Sc3N@Ih-C80 metallofullerene is influenced by the identity of the electron donating/accepting group on the aromatic solvent.
