Fig. 1: Compounds used here and characterization of micellar solutions formed from these.

a Chemical structures of the four azobenzene-dipeptides used here. The amino acids used are named using one letter codes; b photographs of solutions formed from each azobenzene-dipeptide in water at pH 10.5 at a concentration of 10 mg mL⁻¹; c SAXS data for each azobenzene-dipeptide in water at pH 10.5 at a concentration of 10 mg mL⁻¹ (black, Azo-FF; blue, Azo-FI; orange, Azo-FV; green, Azo-FL) with the fits to the data shown as red lines; d viscosity data for each azobenzene-dipeptide in water at pH 10.5 at a concentration of 10 mg mL⁻¹ (black, Azo-FF; blue, Azo-FI; orange, Azo-FV; green, Azo-FL). The data are plotted as the average of three measurements, with the error bars representing the standard deviation.
