a Time-dependent HER of DCP and PFBPO photocatalysts under 380–780 nm irradiation (5 mg of polymer powder and 10 mL of a mixed solution consisting of 33.3 vol.% H2O, 33.3 vol.% MeOH, and 33.3 vol.% TEA). b Concentration dependence of the HER over PFBPO, P-HEG-10, and P-HEG-20. c Linear relationship between the HER and the quantity of photocatalytic solution (10, 15, and 20 mL of solution with a constant P-HEG-10 concentration). d Correlation between the apparent quantum yield (AQY) and the UV-vis absorption spectra of P-HEG-10. e HER values in the absence of MeOH (i.e., in an 80 vol.% H2O/20 vol.% TEA solution) over PFBPO, P-HEG-10, and P-EA-5 (L columns) compared to the HER values in presence of MeOH (i.e., in a 33.3 vol.% H2O/33.3 vol.% MeOH/33.3 vol.% TEA solution) (R columns). f Comparison of the time-dependent HER over P-HEG-10, PFBPO, and PFTEGBPO using the same photocatalytic conditions as used in a.
