The divergent supramolecular behavior of a series tripeptide stereoisomers was elucidated through spectroscopic, microscopic, crystallographic, and computational techniques. Only two epimers were able to effectively self-organize into amphipathic structures, leading hydrogels or crystals, respectively. Despite the similarity between peptides' turn conformations, stereoconfiguration led different abilities engage in intramolecular hydrogen bonding. Self-assembly further shifted pKa value C-terminal side chain. As result, across pH range 4–6, only one epimer predominated sufficiently as zwitterion reach critical molar fraction, allowing gelation. By contrast, differing values higher dipole moment other favored crystallization. four tested for gold nanoparticle (AuNP) formation, with hydrogel being key control stabilize AuNPs, yielding nanocomposite that catalyzed photodegradation dye. Importantly, AuNP formation occurred without use reductants than peptide, redox chemistry investigated by LC–MS, NMR, infrared scattering-type near field optical microscopy (IR s-SNOM).
