Supramolecular interaction of fullerenes with cyclic dimers of metalloporphyrins ( 1 ‐M, M=central metal ions) showed a pronounced dependence on the nature of the metal ions, whereby 1 ‐RhMe/fullerene systems displayed extremely high association constants (ca. 10 8 M −1 ) and low dissociation activities. Crystal‐structure analysis and NMR data suggested a charge‐transfer interaction and van der Waals interactions between the host and guest.
