Abstract
Bipolar electrochemistry (BE) combined with electrochemiluminescence (ECL) has gained considerable attention as a versatile and powerful analytical technique operating in a wireless manner. However, only co-reactant ECL has been reported so far when using a BE setup. In this work, the generation of annihilation ECL at the anodic extremity of a bipolar electrode (BPE) is demonstrated in two different spatial arrangements of the electrodes. The reported approach is based on a synergetic effect between the asymmetric electroactivity induced across the BPE, which produces different redox states of [Ru(bpy)3]2+, and the electro-migration mechanism of the formed ionic species, allowing the localization and concentration of the ECL emission. The presented approach demonstrating annihilation ECL via BE, paves the way for the design of easy and straightforward light-emitting platforms for multiple applications.
期刊介绍：
ChemElectroChem is aimed to become a top-ranking electrochemistry journal for primary research papers and critical secondary information from authors across the world. The journal covers the entire scope of pure and applied electrochemistry, the latter encompassing (among others) energy applications, electrochemistry at interfaces (including surfaces), photoelectrochemistry and bioelectrochemistry.
