Schematic representation of the pH responsive supramolecular polymer formation of NDI-L-Glu (1); (A) at pH 3; amide H-bonding and expected π-π staking interactions; (B) at pH 7; H-bonding, amide H-bonding and expected π-π staking interactions; (C) at pH 9; electrostatic repulsion, amide H-bonding and expected π-π staking interactions.
