Anion-driven supramolecular gel: naked-eye detection of picric acid, facilitating in situ formation of gel nanocomposites and enabling solid-state anion exchange

GUA-IND forms stimuli responsive anion-induced supramolecular gel (GI-G) which forms nanocomposites with metal salts that show antioxidant and antimicrobial activities. GUA-IND also exhibits anion exchange phenomena in the solid state.
