Anion binding properties of triindolylmethane was investigated by 1H NMR spectroscopy in CDCl3. Triindolylmethane selectively binds chloride anion over other anions tested. This selectivity will be attributed to the proper size of the binding pocket for chloride anion and the formation of the multiple hydrogen bonds between three indole NHs and chloride anion.

Keywords: Triindolylmethane, chloride anion selectivity, anion recognition, hydrogen bond, quaternary ammonium salt
