Fig. 4: Nano-imaging analysis of morphology and supramolecular assembly state of χ- and rac-polymer chains.
From: Unravelling emergence of chirality in click-chemistry polymers down to the single-chain level
a AFM morphology maps of χ- (left) and rac- polymers (right). b Box plot comparing single-molecule volume-based molecular weight and polydispersity estimations by AFM (orange) and bulk GPC measurements (green) for χ- (left, n = 33) and rac-polymers (right, n = 42); error bars represent SD. Ultra-high resolution AFM of morphology (brown-yellow) and amplitude error (blue) of single polymeric chains for (c) χ-polymer and (d) rac-polymer chains, together with their cross-sectional profile (smoothed using 3 pixels adjacent averaging, and a 7-points, 2nd order Savitzky-Golay filter). e AFM morphology map and cross-sectional profiles of the supramolecular assemblies of rac-polymers, made of one (red), two (orange), three (blue), four (green) chains. f Box plot comparing the cross-sectional width of single (red) and assembled two (orange), three (blue), and four (green) rac-polymer chains (n = 96); each data point is the width of a polymer, and box plot has one SD as whiskers.
