It is highly desired to explore closely contacted polymer semiconductor/g-C3N4 heterojunction photocatalysts with promoted photogenerated-carrier separation and extended visible-light response for efficient visible-light-driven H2 production. Here, we first synthesized the nitro-terminated oligothiophene (OTh) by controlled copolymerization of thiophene 2-nitrothiophene monomers, then constructed oligothiophene/crystallinity-improved g-C3N4 (OTh/g-C3N4) heterojunctions a grinding-induced combination strategy. The ratio-optimized 20OTh5/g-C3N4 shows production activity up 3.63 mmol h-1 g-1 under irradiation, ∼25.9-time enhancement compared that g-C3N4. As verified time-resolved photoluminescence spectra, surface photovoltage fluorescence spectra related •OH amounts, improved photocatalytic due transfer in expanded response. also confirmed OTh chain length, crystallinity, tight interface contact dependent on hydrogen bonds N···S interactions between are reasonable enhanced electron from This work illustrates feasible strategy construct solar-light-driven
