An attractive feature of supramolecular polymers is their reversibility — they typically depolymerize upon heating. Now, in the presence of a scavenger molecule, a metalloporphyrin derivative bearing eight amide-containing side chains has been shown to undergo supramolecular polymerization on heating as well as cooling through π-stacking and multivalent hydrogen-bonding interactions.
