N2 - The short exciton diffusion length (LD) associated with most classical organic photocatalysts (5-10 nm) imposes severe limits on photocatalytic hydrogen evolution efficiency. Here, a photovoltaic molecule (F1) without electron-deficient units at the central building block was designed and synthesized to improve the photoluminescence quantum yield (PLQY). With the enhanced PLQY of 9.3% and a large integral spectral overlap of 3.32 × 1016nm4M-1cm-1, the average LDof F1 film increases to 20 nm, nearly twice the length of the control photovoltaic molecule (Y6). Then, the single-component organic nanoparticles (SC-NPs) based on F1 show an optimized average hydrogen evolution rate (HER) of 152.60 mmol h-1g-1under AM 1.5G sunlight (100 mW cm-2) illumination for 10 h, which is among the best results for photocatalytic hydrogen evolution.
