Resumen:
Novel functionalized conductive polymers are synthesized using modification reactions of polyaniline: combinatorial diazonium coupling, nucleophilic addition and N-nitrosation. To perform combinatorial modification, azo dyes, bearing terminal aromatic amino groups, are synthesized combinatorially using commercially available aromatic amines. The dyes are then diazotized and coupled with polyaniline. The properties of the conductive polymer is altered, making the products soluble in common solvents, albeit with a relatively small decrease in conductivity. It is also shown that  nucleophilic addition to oxidized polyaniline could be controlled, chemically or electrochemically, by the oxidation state of the polymer. Reversible nitrosation reaction is used to design lithographic and  photolithographic processes to deposit PANI patterns.
