Electrifying synthesis is now a common slogan among synthetic chemists. In addition to the conventional two- or three-electrode systems that use batch-type cells, recent progress in organic electrochemical processes has been significant, including microflow electrochemical reactors, Li-ion battery-like technology, and bipolar electrochemistry. Herein we demonstrate an advanced electrosynthesis method without the application of electric power based on the concept of streaming potential-driven bipolar electrochemistry. As a proof-of-concept study, the electrochemical oxidative polymerization of aromatic monomers successfully yielded the corresponding polymer films on an electrode surface, which acted as an anode under the flow of electrolyte in a microchannel without an electric power supply.
电合成如今已成为合成化学家们常用的口号。除了使用间歇式电池的传统两电极或三电极系统外，有机电化学过程近年来取得了显著进展，包括微流电化学反应器、锂离子电池类技术以及双极电化学。在此，我们基于流动电势驱动的双极电化学概念，展示了一种无需施加电力的先进电合成方法。作为概念验证研究，芳香族单体的电化学氧化聚合在电极表面成功生成了相应的聚合物膜，该电极在无电源供应的微通道中电解质流动情况下充当阳极。
