Hemicarceplex formation allows ready identification of the isomers of the metallofullerene Sc<sub>3</sub>N@C<sub>80</sub>using<sup>1</sup>H and<sup>13</sup>C NMR spectroscopy
A cyclotriveratrylene-based molecular cage forms hemicarceplexes that significantly increase the solubility of commercially available Sc3N@C80in CDCl3.
Hemicarceplex Formation With a Cyclotriveratrylene-Based Molecular Cage Allows Isolation of High-Purity (≥99.0%) C<sub>70</sub> Directly from Fullerene Extracts
A cyclotriveratrylene-based molecular cage that favors the formation of a room temperature isolable hemicarceplex with C-70, in the presence of C-60, has been developed. Significant differences in the association and dissociation kinetics of the molecular cage and buckyballs allowed the isolation of C-70 in high purity (>= 99.0%) from a commercial fullerene extract without the need for recrystallization or HPLC.
