Abstract Hydrogen peroxide (H 2 O ) is an environmentally friendly reagent, and organic semiconductors (OSCs) are ideal photocatalysts for the synthesis of H due to their well‐defined molecular structure, strong donor‐acceptor interactions, efficient charge separation. This review discusses regulatory mechanisms functional group modifications in tuning photocatalytic performance OSCs, highlighting relationship between structure catalytic performance. For example, electron‐regulating groups, such as cyano halogen, induce dipoles, facilitating migration photogenerated electrons. Fluorine groups optimize band prolong carrier lifetime high electronegativity. π‐Conjugated extension like anthraquinone thiophene, expand conjugation, improve visible light capture, stabilize intermediates through redox cycles. Hydroxyl enhance surface hydrophilicity promote activation, while imine bond protonation adjusts distribution improves selectivity cycle stability. Multi‐active site sulfonic acid amide, accelerate reaction kinetics inhibit decomposition. Functional absorption, separation, reactions electronic regulation, intermediate adsorption optimization, proton‐electron transfer. Future work should integrate machine learning identify optimal combinations develop green functionalization strategies photocatalyst synthesis.
