Azulene–boronate esters: colorimetric indicators for fluoride in drinking water

• Low cost andin situfluoride detection by non-experts is importantfor the determination of drinking water safety in developing countries.Colour reagents can provide results quickly without expensiveequipment, but colorimetric fluoride indicators are often non-specific, complex to use or do not work in water. Here we showthat azulene–boronate indicators respond selectively to fluoride atconcentrations relevant to the WHO limit of 1.5 mg L1.
