Tubular crystals growth for a nanoporous hydrogen-bonded metal–organic framework
Résumé
A supramolecular architecture formed by H-bonded assemblage of ditopic bisimidazoliumbenzene cations with anionic metal-oxalate modules shows permanent porosity upon guests release; the reversible sorption process being accompanied by crystal-to-crystal transformations. Additional macroporosity for the material was achieved by controlled growth of crystals with tubular morphology.
