文摘

A simple dual sensing of CN⁻ and Ag⁺ was first time reported by naphthalene based lab-on-a-molecule containing benzothiazole in DMF buffered aqueous solution. With CN⁻ and Ag⁺, probe class="boldFont">1 showed highly selective and sensitive responses towards CN⁻ and Ag⁺ in both UV–Vis and fluorescence channels over other tested ions. Meanwhile, the sensing mechanism of both title ions was further studied by NMR titration and XPS experiments.
