A comprehensive review of the imidazole, benzimidazole and imidazo[1,2- a ]pyridine-based sensors for the detection of fluoride ion

detection. A special review focusing solely on fluoride sensing by the imidazole-based moiety has not yet been addressed. Imidazole compounds have surged in prominence over the last few years, making them particularly desirable for developing efficient, sensitive, and selective fluoride detection methods. The present review concisely represents the contribution of a wide variety of imidazole fluorophores for fluoride ion detection.
