Abstract

Simple dual sensing of Zn²⁺ and CN⁻ was reported for the first time using the triphenylamine based lab-on-a-molecule TATP in both UV-Vis and fluorescence channels over other tested ions. Meanwhile, the sensing mechanism for both title ions was further studied using NMR titration and DFT calculations.
