Bioinorganic reaction centres on electrodes. Modified electrodes possessing amino acid, peptide and ferredoxin-type groups on a poly(pyrrole) backbone

摘要: Some amino-acid and peptide derivatives of pyrrole such as the N,N′-bis{N-[3-pyrrol-1-yl)propanoyl]-glycyl}-L-cystine methyl ester have been synthesised characterised. The functionalised pyrroles undergo facile electropolymerisation to give electrode-bound films which are conducting in oxidised state. Cystine-derivatised co-polymers can be converted a cysteinyl state allows binding ferredoxin centres. Activated pentafluorophenyl esters provide convenient route derivatised monomers. Importantly, an active covalent modification after polymerisation with, for example, redox-active ferrocenemethanol.
