(a) CV curves of 2.0 mM of chemosensor 1 in absence (—: inversion potential  V; ∙ ∙∙: inversion potential  V) and in presence of 1.0 mM of Cd²⁺ (– – –). (b) CV curves of 2.0 mM of chemosensor 2 in absence (—: inversion potential  V; ∙ ∙∙: inversion potential  V) and in presence of 0.5 equivalent of Cd²⁺ (– – –). Voltammograms were recorded in ACN containing 0.1 M TBABF₄ as supporting electrolyte. Working electrode: glassy carbon; reference electrode: SCE (KCl 3 M); scan rate: 0.1 Vs⁻¹.
