Abstract

X-ray diffraction. This framework is sustained by π-stacked tectons linked through one-dimensional helical chains of C-I⋯N halogen bonding, yielding full three-dimensional connectivity. Subtle torsional disorder within these chains can be resolved crystallographically, providing rare insight into molecular-level disorder in highly ordered porous frameworks. For comparison, study of an analogous hydrogen-bonded framework composed of a point-modified tecton found rapid structural reorganization upon solvent exchange, supporting more robust intermolecular connectivity in the halogen-bonded system. This work defines a new upper bound for halogen bonding in materials design, establishing XOFs as a distinct permanently porous materials platform.
