文摘

Specific recognition of CN⁻ in sodium cyanide solution was achieved using two imidazole-based receptors (A and B). Visually detectable color changes were associated with the formation of hydrogen bonded adducts, A·CN⁻ and B·CN⁻. Ratiometric fluorescence response was achieved for receptor A on binding to CN⁻, and this reagent was used for imaging bacterial cells pre-exposed to 1.42 μM CN⁻ solution.
