Like peas in a pod : X‐ray crystallography reveals a self‐assembled nanotube of cyclic porphyrin dimers and its inclusion complex with C 60 (see picture, N blue, Ni green). The cyclic molecules stack through nonclassical CH⋅⋅⋅N hydrogen bonds and π–π interactions of pyridyl groups to form the tubular structure. The C 60 molecules are linearly arranged to form a supramolecular peapod.
