Metal–peptide rings and nets with entangling topologies

Construction of topological molecules has long attracted chemists, yet synthetic strategies for highly complexed topologies remain unexplored to date. In this talk, our recent achievements by using metal–peptide strands will be introduced. Our folding-and-assembly strategy, based on a cooperative processes of peptide self-folding and metal-induced self-assembly, has shed light on the latent entangling nature of peptides and enabled advanced topological nanostructures. Remarkable examples such as torus knots, polyhedral links, and spherical nets will be discussed.
