Aromatic nanochannels were assembled about linear π‐conjugated molecules. The novel supramolecular architectures are cemented by weak interactions and form crystals that melt at much higher temperatures than the standard molecular arrangement. The perfect fitting of the chains in the unusual environment is shown by the close contacts of 2.5 Å that occur between guest hydrogen atoms and the surrounding aromatic groups (see picture).
