title: A simple isomeric separation of D5h and Ih Sc3N@C80 by selective chemical oxidation.
abstract: Two electrochemical oxidation waves assigned to the D(5h) isomer of Sc(3)N@C(80) have been identified, and a 270-mV difference in the first electrochemical oxidation potentials of the I(h) and D(5h) isomers has been measured. On the basis of this oxidative potential difference, a strategy for isomeric purification involving a selective chemical oxidation of the D(5h) isomer is reported. Variable scan cyclic voltammetry of the resultingly pure Sc(3)N@C(80) I(h) isomer shows evidence of a rapid endohedral chemical reaction following the first reduction process.
