2025 IRG-2: Redox-Enabled Pathway Complexity in Supramolecular Hydrogels

May 22, 2025

This paper reports:

  • Redox-enabled pathway complexity in amino acid-functionalized perylene diimides (PDIs) and its consequence for the macroscopic hydrogel network.
  • Chemical reduction and subsequent oxidation enable a kinetically trapped state of the micellar network, which transforms into different network morphologies in response to heat and time.
  • Pathway complexity in supramolecular systems can alter bulk material properties

Impact:

  • Our finding suggests the potential for future development of dynamic materials that achieve multiple macroscopic functions with a single building block.
