A novel reaction-based, chromogenic and “turn-on” fluorescent chemodosimeter for fluoride detection

Abstract

A reactivity based fluoride sensing method exploiting both its nucleophilic and basic character has been developed. This novel dual mode strategy offers both a visible “naked-eye” and a “fluorescence-on” detection. Upon nucleophilic addition of F⁻ to fluorochromic maleimides this approach allows for selective detection of fluoride from other (critical) basic anions, such as acetate, hydroxide or cyanide.
