Abstract

AbstractMetals play an important role in the structure and functions of various proteins. The combination of metal ions and peptides have been emerging as an attractive field to create advanced structures and biomaterials. Here, we are reporting the anion‐influenced, silver ion coordinated diverse networks of designed short tripeptide 310‐helices with terminal pyridyl groups. The short peptides adopted classical right‐handed, left‐handed and 310EL‐helical conformations in the presence of different silver salts. The peptides have displayed conformational flexibility to accommodate different sizes and interactions of anions to yield a variety of metal‐coordinated networks. The complexes of metal ions and peptides have shown different porous networks, right‐ and left‐handed helical polymers, transformation of helix into superhelix and 2 : 2 metal‐peptide macrocycles. Further, the metal‐peptide crystals with inherent dipoles of helical peptides gave striking second harmonic generation response. The optical energy upconversion from NIR to red and green light is demonstrated. Overall, we have shown the utilization of short 310‐helices for the construction of diverse metal‐coordinated helical networks and notable non‐linear optical effects.
