Simple (S)- or (R)-1,1′-binaphthalene-2,2′-diol-3-carbaldehyde was found to enantioselectively self-assemble to form a gel or solution with one enantiomer of chiral amines, 1,1′-binaphthalene-2,2′-diamine, through intermolecular hydrogen bond, H⋯H, π–π stacking, and chirality-induced interactions. The enantioselective recognition is visual and highly selective with little interference from similar organic compounds and common cations and anions.
