a Schematic illustration of seeded living supramolecular polymerization. b AFM height image of M3Seed spin-coated on a silicon wafer. Cross-section was measured along the blue line. c Histogram of the length distribution of M3Seed. d Time course of supramolecular polymerization of M3 initiated by addition of different amounts of M3Seed ([M3]/[M3Seed] = 50:1 (pink curve), 100:1 (green curve), 150:1 (blue curve), 200:1 (yellow curve) v/v). e Log-log plot of the rate of polymerization as a function of M3Seed concentration. Error bars correspond to one standard deviation of a triplicate measurement. Solid line – linear fit with slope 0.97 (correlation coefficient 0.998). f Weight-average length (Lw), number-average length (Ln) and PDI (Lw/Ln) obtained by measuring AFM length of supramolecular polymers obtained with different [M3]/[M3Seed] ratios (3:1, 5:1, 7:1, 10:1 v/v) plotted against [M3]/[M3Seed] v/v. Solid lines represent linear fit (correlation coefficients 0.995) indicating linear dependence of the size of supramolecular polymers on the amount of M3Seed added. Dashed line serves as guide for the eye. g–i Representative AFM height images of supramolecular polymers obtained with different [M3]/[M3Seed] ratios ((g) 5:1, (h) 10:1, (i) 50:1 v/v) spin-coated on silicon wafer.
