Abstract

Two electrochemical oxidation waves assigned to the D5h, isomer of Sc3N @ C80 have been identified, and a 270-mV difference in the first electrochemical oxidation potentials of the I h and D6h, isomers has been measured. On the basis of this oxidative potential difference, a strategy for isomeric purification involving a selective chemical oxidation of the D5h isomer is reported. Variable scan cyclic voltammetry of the resultingly pure Sc3N @ C80 Ih isomer shows evidence of a rapid endohedral chemical reaction following the first reduction process.
