Abstract

The availability of isomerically pure samples of metallic nitride fullerenes (e.g., Sc3N@C-80) is paramount for accurate characterization and experimentation. In this Communication, we report a rapid (13 h) removal of contaminant D-5h Sc3N@C-80 isomer and the subsequent isolation of large quantities (0.112 g) of isomerically pure I-h Sc3N@C-80 metallofullerenes using a diaminosilica "Stir and Filter Approach" process. Confirmation of D-5h isomer removal is obtained via HPLC and electrochemical analysis.
