Making molecular nanotubes by cross-linking stackable rings

briefing Making molecular nanotubes by cross-linking stackable rings Discrete chiral nanotubes have been synthesized with high efficiency by connecting rimdesymmetrized macrocycles through dynamic covalent linkages.These 2-nm long and 4.7-Å wide helical covalent organic pillars, resolved by chromatography and characterized by X-ray crystallography, show strong binding affinities for linear guest molecules with complementary lengths and electronic densities.
