Functional Groups‐Regulated Organic Semiconductors for Efficient Artificial Photosynthesis of Hydrogen Peroxide

Abstract Hydrogen peroxide (H 2 O 2 ) is an environmentally friendly reagent, and organic semiconductors (OSCs) are ideal photocatalysts for the synthesis of H 2 O 2 due to their well‐defined molecular structure, strong donor‐acceptor interactions, and efficient charge separation. This review discusses the regulatory mechanisms of functional group modifications in tuning the photocatalytic performance of OSCs, highlighting the relationship between functional group structure and catalytic performance. For example, electron‐regulating groups, such as cyano and halogen, induce molecular dipoles, facilitating the migration of photogenerated electrons. Fluorine groups optimize the band structure and prolong carrier…
