Organic cathode materials (OCMs) have tremendous potential to construct sustainable and highly efficient batteries beyond conventional Li-ion batteries. Thereinto, quinone/pyrazine hybrids show significant advantages in material availability, energy density, cycling stability. Herein, we propose a facile method synthesize hybrids, i.e., the condensation reaction between ortho-diamine bromoacetyl groups. Based on it, successfully synthesized three 1,4-diazaanthraquinone (DAAQ) dimers, including 2,2′-bi(1,4-diazaanthraquinone) (BDAAQ) with an exceptional theoretical capacity of 512 mAh g–1 based eight-electron reaction. It can be fully utilized Li wide voltage range 0.8–3.8 V, at cost inferior In optimal 1.4–3.8 BDAAQ exhibits one best comprehensive electrochemical performances for small-molecule OCMs, high specific 366 g–1, average discharge 2.26 as well respectable retention 59% after 500 cycles. Moreover, in-depth investigations reveal redox mechanisms C═O C═N groups fading dissolution–redeposition behaviors. brief, this work provides instructive synthesis mechanism understanding high-performance OCMs hybrid structure.

Abstract: Electro-organic synthesis, an atom-efficient, sustainable, mild process, permits ecofriendly and elegant green path to synthesize structurally complex, still valuable molecules, avoiding the use of conventional harsh oxidizing reducing agents long-route reaction protocols. Being one oldest forms setups in a laboratory, it deals with fundamental redox chemistry through direct application electrical potential. Here flow electrons acts as agent at anode same time cathode, depending upon requirement reaction. Simultaneously, minimizes generation reagent waste during However, electrifying organic synthesis plays more than preventing footprint. This technology provides alternative roadmap nonclassical bond disconnections access desired target molecules by cutting down number steps formation apparently looking difficult bonds excellent regio-, chemo-and stereoselectivity. Hence, emerges attractive technique for contemporary synthetic communities. Consequently, recent years, multiple milestones have been achieved electro-organic fascinating natural products oxidative C-C formation, C-H/N-H functionalization, very rare N-N dimerization, RCDA etc. Thus, extremely complex finding new electro-synthetic route key methodology become alluring targets chemists because their versatile utilities medicine, agriculture, food, cosmetic industry. review presents advances electrochemistry total 20 reported since 2013. Enabling are analyzed alongside innate advantages well future prospects speculated.

Abstract Aqueous organic flow batteries (AOFBs) hold great potential for large‐scale energy storage, however, scalable, green, and economical synthetic methods stable redox‐active molecules (ORAMs) are still required their practical applications. Herein, pyrene‐based ORAMs obtained via an in situ electrolysis strategy a cell. It is revealed that the water attacking pyrenes restructured to produce variety of isomers dimers during electrolysis, which can be modulated by regulating local electron cloud density steric hindrance pyrene precursors. As result, molecularly reconfigured catholytes, even without any further purification, achieved high electrolyte utilization ≈96% volumetric capacity above 50 Ah L −1 . Inspiringly, remarkable cell stability with almost no decay ≈70 days achieved, benefiting from robust aromatic structure cores. The insights into electrosynthesis provided work will provide guidance designing ultra‐stable AOFB
