Binaphthyl-Based Chiral Macrocyclic Hosts for the Selective Recognition of Iodide Anions.

ABSTRACT: In this study, we explorethe synthesis of binaphthyl-based chiral macrocyclic hosts for the first time. They exhibited the selective recognition abilities of iodide anions which can be favored over those of other anions (AcO^-, NO₃^-, ClO₄^-, HSO₄^-, Br^-, PF₆^-, H₂PO₄^-, BF₄^-, and CO₃F₃S^-), as confirmed by UV-vis, HRMS, and ¹H NMR spectroscopy experiments, as well as DFT calculations. Neutral aryl C-H···anion interactions play an important role in the formation complexes. The recognition process can be observed by the naked eye.
