Cartoon representation of a proposed structure of the supramolecular complexation at the polymer chain ends. The cooperative interactions between water, NPrMal and the complexation of MePip to the Zn-center in the porphyrin stabilize the free chain end of the supramolecular polymer. This stabilization eventually leads to the gradual breakdown of the supramolecular polymer. Experimental evidence for the interactions is indicated by gray text.
