Versatile and controllable nanostructures derived from peptide self-assemblies have been used in various research areas. Herein, we incorporated a short peptide unit, Fmoc-diphenylalanine (FmocFF), into a deep eutectic solvent. This integration resulted in a supramolecular gel displaying ion-conductive, self-healable, and biodegradable properties. The nanostructural features of FmocFF eutectogel were examined using SEM, FT-IR, and CD spectroscopies. Subsequent kinetic investigations revealed the distinctive gelation pathways for FmocFF eutectogel. We then evaluated the functional properties of FmocFF eutectogel using rheological measurements, EIS, and enzymatic degradation assay. Additionally, we applied the eutectogel as an electrolyte for thermoelectric materials and observed a Seebeck effect under varying temperatures. Our findings could provide insights into the gelation behavior of peptide-based building units and suggest promising avenues for sustainable ionic soft materials.
