A wide variety of covalent organic cages and two- and three-dimensional covalent organic frameworks have been obtained through dynamic covalent chemistry, yet the synthesis of their one-dimensional counterparts has remained challenging. Porous covalent organic nanotubes have now been prepared through reversible aldehyde–amine condensation and it has been shown that these can further assemble into toroidal architectures.
