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.
