Year: 2026
Type: preprint
Abstract: Wireless bipolar electrochemistry (BPE) has emerged as a powerful platform for organic electrosynthesis, enabling redox transformations on electrically floating conductors without direct electrical wiring. Through electric-field-induced polarization, bipolar electrodes simultaneously promote spatially separated oxidation and reduction reactions, offering unique opportunities for reaction design, miniaturized reactor architectures, parallel processing, and sustainable chemical synthesis. Recent years have witnessed significant advances in both exogenous and endogenous bipolar electrochemical systems, expanding the scope of wireless electrosynthesis to asymmetric transformations, flow chemistry, low-electrolyte conditions, autonomous microreactors, and self-propelled electrochemical systems. This review critically examines the fundamental principles governing bipolar electrochemistry, recent developments in organic synthesis, and emerging diagnostic methodologies, including split bipolar electrodes and electrochemiluminescence-based imaging, which have substantially improved mechanistic understanding of charge transport, polarization phenomena, and reaction control. The advantages and limitations of wireless bipolar systems are evaluated in comparison with conventional electrolysis, highlighting challenges associated with reaction selectivity, scalability, energy efficiency, and quantitative electrochemical characterization. Finally, future opportunities involving advanced materials, operando analytical techniques, artificial intelligence-assisted optimization, and continuous-flow processing are discussed. Collectively, these developments position wireless bipolar electrochemistry as a promising enabling technology for next-generation sustainable electrosynthesis and autonomous electrochemical manufacturing.
