RESUMEN
Construction of single-component supramolecular triangle and unprecedented spontaneous resolution of pairs of intertwined supramolecular 31 - and 32 -double helices by the self-assembly of achiral 2-(iodoethynyl)pyridine and its derivatives have been achieved through intermolecular ethynyl C-Iâ â â â N halogen bonds in the crystalline state. Fine-tuning of the molecular structure of the achiral monomer and choice of solvents for crystallization have a dominant effect on the resultant supramolecular architectures.
