Design and characterization of ferrocene–peptide–oligoaniline conjugates

Ferrocene–peptide–oligoaniline conjugates were designed by the introduction of two ferrocene–peptide conjugates into a π-conjugated phenylenediamine spacer to demonstrate the luminescent switching by changing the redox states of the π-conjugated phenylenediamine moiety, wherein the self-aggregation of the π-conjugated moiety was achieved in a higher concentration to induce the chirality organization with a red shift of the maximum emission wavelength.
