Take the tube : Self‐organization of shape‐persistent macrocycles in the liquid‐crystalline phase by π–π stacking leads to empty nanochannels that have an inner diameter above one nanometer and either tight or more permeable walls (see picture). Solid‐state NMR spectroscopy was used to confirm that the channels do not contain solvent molecules or alkyl chains.
