New electropolymerizable aromatic compounds (i.e. pyrrole, thiophene, aniline) bearing boronic acid and ester substituents have been synthesized and their electrochemical behavior has been investigated. Functionalized polythiophene and polypyrrole films could be anodically generated in acetonitrile, whereas the polyaniline derivative was electroformed in an acidic aqueous solution. The electrochemical responses of some of these materials were changed when fluoride ions were added to the electrolytic solutions. The strongest modifications, caused by binding of fluoride by the immobilized boron, were observed for the polypyrrole derivative in hydroorganic media.
Chemical synthesis at solid interfaces. On the use of conducting polythiophenes equipped of adequate linkers allowing a facile and highly selective cathodic S-N bond scission with a fully regenerating resin process

Electrogenerated polythiophenes were evaluated as Merrifield-like resins for the anchoring of amine functions together with deprotection processes. Suitable linkers were terminated with a fully regenerable aromatic sulfonamide moiety. The S-N bond was cleaved to liberate the amine with high selectivity under very mild conditions by cathodic means with amine liberation. Moreover a facile recycling process of the resin allows the further grafting of various amine functions.
