Abstract
Two newly synthesised 21 - amino acid peptides based on L-leucine and L-lys ine substituted with ferrocene groups preserve the helical structure of the peptide and behave as multi-centre donor systems with six electroactive re versible redox centres per molecule. The formal potential of the hexaferroc ene compound is slightly less positive than that of its single centre analo gue. CT interactions of the ferrocene peptides with chloranil are not confi rmed by UV-vis spectra. (C) 2001 Elsevier Science B.V. All rights reserved.
