a) Comparison of the photocatalytic hydrogen evolution activities of F8BT prepared without photocrosslinker and with CL‐C2, CL‐C11, and CL‐TEG using ascorbic acid (pH 4) as a sacrificial agent (λ > 420 nm). b) Hydrogen evolution rate (HER) for each sample (the average of 5 h across five repeated runs). c) Photocatalytic stability tests up to 20 h for optimized F8BT nanoparticles photorosslinked via CL‐TEG. d) Apparent quantum yield (AQY) of F8BT photocrosslinked via CL‐TEG at 400, 420, 450, 500, and 550 nm along with the absorbance spectrum of a 0.2 m (pH 4) solution of ascorbic acid. The error bars were obtained from the five standard deviation derived from five repeated trials.
