Extended Data Fig. 1: Separation of toroids from elongated fibres via thermal reorganization followed by membrane filtration.
From: Self-assembled poly-catenanes from supramolecular toroidal building blocks
a, AFM image of supramolecular polymers obtained by heating a quenched solution of 1 (cT = 1 × 10−4 M) in MCH/CHCl3 (9:1 v:v) at 363 K for 5 min and subsequently cooling to 293 K at a cooling rate of 1.0 K min−1. b, AFM image of supramolecular polymers obtained after passing the resulting solution through a membrane filter with a pore size of 200 nm. The samples were spin-coated onto a HOPG substrate at 293 K. Scale bars, 100 nm.
