Helical aromatic foldamers with tubular cavities capable of accommodating multiple halide ions

Abstract

A series of pyridinium–indolocarbazole oligomers with different lengths, capable of adopting helical conformations with tubular cavities, has been synthesized. These oligomers can accommodate two, three, or four iodide ions in a linear arrangement within their cavities, which can be exchanged with other halides.
