Extended Data Fig. 2: AFM images of supramolecular polymers obtained in various n-alkanes by single-injection solvent-mixing experiment.
From: Self-assembled poly-catenanes from supramolecular toroidal building blocks

a–f, AFM images of supramolecular polymers prepared by injecting a 100-μl chloroform solution of 1 (1 × 10−3 M) into 900 μl of n-hexane (a), n-heptane (b), n-octane (c, d), n-nonane (e) or n-decane (f) in one portion. Nano-[n]catenanes with n = 2, 3, 4, 5, 6 are shown by dashed white, blue, green, red and pink circles, respectively. The samples were spin-coated onto a HOPG substrate at 293 K. Scale bars, 100 nm.
