|a While the interest in hydrogen photocatalysis from organic semiconductors is rapidly growing, there is a necessity to achieve hydrogen production without platinum (Pt), considering its price, availability and toxicity. In this work, this is demonstrated that high hydrogen evolution reaction (HER) efficiencies can be achieved without the use of Pt. A series of low-cost conjugated polymers are designed around the dibenzothiophene-S,S-sulfoxide (BTSO) unit, and self-assembled as nanoparticles in water via the nanoprecipitation technique. This is highlighted that how side chain engineering, nanoparticle morphology and pH influence the hydrogen evolution rate. Optoelectronic properties are improved through a Donor-Acceptor structure, resulting in an unprecedented hydrogen evolution reaction rate of 209 mmol g-1 h-1 in the absence of Pt. A clear correlation between high efficiencies and number of BTSO units within the polymer backbone can be established. The design rules pioneer the design of future organic materials is presented for a cost-efficient and sustainable hydrogen photocatalysis
