Crease crossing peptide embossing: The first tripeptide ferrocene foldamers to adopt an extended β-sheet-like structure in solution and solid state are presented. The flexibility of peptide substituents in 1,n′-ferrocene-bispeptide conjugates was thought to prevent the formation of extended β-sheet foldamers. The results suggest that ferrocene is a valuable scaffold for extended β-sheets.
