For example, the triscatehchol-Fe3+ can restore its cohesiveness and shape after being torn. Chain-folding polyimide and pyrenyl-end-capped chains give rise to supramolecular networks.
The ability of triscatechol-Fe3+ to reform its structure after damage is comparable to the way some materials can regain their shape or integrity. The use of chain-folding polyimide and pyrenyl-end-capped chains enables the creation of supramolecular networks with unique properties.
