Recently, linear conjugated polymers have significant advantages, especially over other organic photocatalysts, with easily fine-tunable optical, physical, and chemical properties. Among them, the ethylene glycol side chain of the linear conjugated polymer increases the surface energy of the polymer nanoparticles, improves the interaction with water, and promotes electron transfer to the water. Moreover, Fluorine substituents in the polymer backbone result in highly ordered lamellar stacks with distinct π-π stacking features. We studied linear conjugated photocatalysts grafted with ethylene glycol side chain and fluorine substituents for hydrogen production. Therefore, the hydrogen evolution rate of 26,000 µmol g-1 h-1 is obtained for copolymers containing both OEG side chains and fluorine substituents under visible light irradiation. (λ > 420 nm)
