Molecularly Tunable Heterostructured Co‐Polymers Containing Electron‐Deficient and ‐Rich Moieties for Visible‐Light and Sacrificial‐Agent‐Free H 2 O 2 Photosynthesis

Abstract As an alternative to hydrogen peroxide (H 2 O 2 ) production by complex anthraquinone oxidation process, photosynthesis of H 2 O 2 from water and oxygen without sacrificial agents is highly demanded. Herein, a covalently connected molecular heterostructure is synthesized via sequential C−H arylation and Knoevenagel polymerization reactions for visible‐light and sacrificial‐agent‐free H 2 O 2 synthesis. The subsequent copolymerization of the electron‐deficient benzodithiophene‐4,8‐dione (BTD) and the electron‐rich biphenyl (B) and p ‐phenylenediacetonitrile (CN) not only expands the π‐conjugated domain but also increases the molecular dipole moment, which largely promotes the separation and transfer of…
