Boosted Durability and Diffusion Kinetics of High‐Potential Azopyridines for Aqueous Organic Flow Batteries

High-potential organic redox-active molecules are crucial for high-energy-density aqueous organic flow batteries (AOFBs). Azopyridine (AZO) derivatives with high redox potential (0.86 V vs. SHE) suffer from structural rearrangement instability and slow redox kinetics during the oxidation process. Herein, we achieve dual-target modulation of the electronic structure and dynamic steric hindrance, which increases the bond energy of the azo bond and buffers the drastic change of redox-induced molecu
