Abstract 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.
