Study of peptide dendrimers having a ferrocene core supported on mercaptoundecanoic acid
Hydrogen-bonding interactions between the carboxylic acid groups of mercaptoundecanoic acid (MUA) coated gold substrates and the ester surface of peptide dendrimers allows the formation of glutamic acid dendrimers films. Dendrimer films were prepared for generations 1-6 (G1-G6) and analyzed by spect...

| Zusammenfassung: | Hydrogen-bonding interactions between the carboxylic acid groups of mercaptoundecanoic acid (MUA) coated gold substrates and the ester surface of peptide dendrimers allows the formation of glutamic acid dendrimers films. Dendrimer films were prepared for generations 1-6 (G1-G6) and analyzed by spectroscopic and electrochemical techniques. Electrochemical studies using cyclic voltammetry and differential pulse voltammetry show that all films except those of G6 were electrochemically active. Lack of activity of G6 films is rationalized by the total encapsulation of the ferrocene redox probe by the dendritic sheath and lack of ion pairing, which prevents its oxidation |
