a The structures of small molecule materials. b The viscosity of polymer and small molecule solution with a concentration of 0.5 mg mL−1 (the average values ± standard deviations for 3 samples). c The diameter distribution of PM6 in chloroform solutions with different concentrations obtained by DLS. d Diameters of polymer-free HJ-NPs (D:A, w:w, 4:6, 0.4 wt.% TEBS/H2O) from TEM, while the diameters of polymer-containing HJ-NPs come from previous literature. e DLS for BTR:L8-BO NPs (D:A, w:w, 4:6, 0.4 wt. % TEBS). f TEM for BTR:L8-BO NPs (D:A, w:w, 4:6, 0.4 wt.% TEBS), and the inset is their diameter distribution. g Photocatalytic HER-m of 50 μg polymer-free NPs (D:A, w:w, 4:6, 0.4 wt.% TEBS, 30 wt.% Pt loading) in 7.5 mL 0.2 M AA aqueous solution at 5 °C, for 4 h under AM 1.5 G, 100 mW cm−2.
