Two series of peptides of different length and rigidity, based on the strongly helicogenic α-aminoisobutyric acid (Aib) residue and containing a terminal ferrocene (Fc) unit, Fc−CO-(Aib)n−OMe (An, n = 1−5, OMe, methoxy) and Z−(Aib)n−NH−Fc (Bn, n = 1−5, Z, benzyloxycarbonyl), were prepared and investigated. We utilized the oxidation-state sensitive, spectroscopic tags of peptides, the CO and NH groups, to map charge delocalization triggered by oxidation of the terminal ferrocene.

Abstract

Two series of peptides of different length and rigidity, based on the strongly helicogenic α-aminoisobutyric acid (Aib) residue and containing a terminal ferrocene (Fc) unit, Fc−CO-(Aib)n−OMe (An, n = 1−5, OMe, methoxy) and Z−(Aib)n−NH−Fc (Bn, n = 1−5, Z, benzyloxycarbonyl), were prepared and investigated. We utilized the oxidation-state sensitive, spectroscopic tags of peptides, the CO and NH groups, to map charge delocalization triggered by oxidation of the terminal ferrocene.
