ECL‐Based Readout of Electric Field‐Induced Fine‐Tuning of Redox Activity
Abstract Magnesium, a highly reactive alkaline earth metal, acts spontaneously as a strong reducing agent. In this work, the redox reactivity of Mg is fine‐tuned selectively in a wireless manner by means of bipolar electrochemistry (BE). This is demonstrated by mapping the spatial electroactivity of...

| description | Abstract Magnesium, a highly reactive alkaline earth metal, acts spontaneously as a strong reducing agent. In this work, the redox reactivity of Mg is fine‐tuned selectively in a wireless manner by means of bipolar electrochemistry (BE). This is demonstrated by mapping the spatial electroactivity of Mg via the electrochemiluminescence (ECL) emission of the Ru(bpy)32+/S2O82− system. Asymmetric ECL patterns are obtained by controlling the applied external electric field. The ECL intensity is increased by up to approximately 80 % at the cathodic extremity whereas a 50 % decrease is observed at the anodic side of a bipolar electrode. Additionally, the influence of the spatial distribution of the electric field on the reactivity of Mg and its concomitant ECL emission is evaluated, producing complex luminescent patterns. These findings, illustrate the wireless modulation of redox reactivity by BE. |
