Abstract:
A new all-hydrocarbon macrocycle, cyclo[8](1,3-(4,6-dimethyl)benzene) (CDMB-8) has been reported. As prepared, it exists in Cₛ symmetry and shows no interaction with fullerenes (e.g., C₆₀ or C₇₀). High temperature (573 K) treatment induces thermal conversion of the material to an isomeric conformer with D₄d symmetry as a receptor for fullerene separation.
