3. Supramolecular polymers with π-π interactions
Colquhoun, Hayes et al.
described back in 2009 one of the first repairable supramolecular systems based on π-π donor-acceptor interactions (π-stacking). This system comprises a low-molecular-weight polydiimide FPA-1 (table
1
) containing numerous electron-deficient sites. This polydiimide is able to fold around the electron-rich sites of the pyrenes located...
