A Nanotube of Cyclic Porphyrin Dimers Connected by Nonclassical Hydrogen Bonds and Its Inclusion of C₆₀ in a Linear Arrangement

Abstract

Like peas in a pod: X-ray crystallography reveals a self-assembled nanotube of cyclic porphyrin dimers and its inclusion complex with C60 (see picture, N blue, Ni green). The cyclic molecules stack through nonclassical CH⋅⋅⋅N hydrogen bonds and π–π interactions of pyridyl groups to form the tubular structure. The C60 molecules are linearly arranged to form a supramolecular peapod.
