Chiral recognition : Silica‐enhanced NMR diffusometry can distinguish the signals of diastereoisomeric mixtures of supramolecular ion pairs (see picture; DOSY=diffusion‐ordered spectroscopy). The experiment has a shorter timescale than liquid chromatography, thus allowing an easier characterization of species that are even configurationally labile on the minutes timescale.
