Triazole-based novel bis Schiff base colorimetric and fluorescent turn-on dual chemosensor for Cu ²⁺ and Pb ²⁺ : application to living cell imaging and molecular logic gates

A novel triazole-based bis Schiff base colorimetric and fluorescent chemosensor ( L ) has been designed, synthesized and characterized. The chemo-sensor L shows its application potential in the detection of Cu ²⁺ and Pb ²⁺ in living cells and building molecular logic gate.
