Abstract

A new dual chemosensor 1was designed and synthesized. Receptor 1 detected Co²⁺ via color change and Zn²⁺ with turn-on fluorescence in a 1:1stoichiometric system, respectively. The response mechanisms of 1-Co²⁺ and 1-Zn²⁺ complexes have been analyzed using UV–vis spectroscopy, fluorescence titration, ESI-mass spectrometry analysis, NMR titration and DFT calculations. Importantly, the detection limit of 1 for Co²⁺was down to 0.34 μM a near-perfect aqueous solution, which is the lowest one among those previously reported for organic chemosensors for sensing of Co²⁺. 1 was also used to quantify Co²⁺ in real water samples.
