Abstract Utilizing semiconductor materials for solar-driven hydrogen production is an alternative to hydrogen generation using fossil fuels. Organic photocatalysts, composed of abundant elements such as C, H, and O on Earth, have the advantage over inorganic catalysts due to their tunable electronic properties through molecular engineering. However, the current understanding of the key properties of their photocatalytic oxidation-reduction process is not complete, hindering further development into more cost-effective and competitive technologies. This paper reviews the progress in organic semiconductor photocatalysis and research on its mechanisms. Starting with the description of charge transfer in organic semiconductors, it outlines the current state of research on the hydrogen evolution reaction (HER) of organic photocatalysts, analyzes the behavior of excitons after photoexcitation, and proposes strategies to improve the efficiency of hydrogen production by organic semiconductor photocatalysis. Finally, it summarizes the research progress on conjugated supramolecular and the development of organic photocatalyst is expected and prospected.
