Pyrrole derivative of viologen was synthesized using the conventional synthetic methodology. The reactivity of positively charged viologen derivatives with charged gold nanoparticles was studied with UV-visible spectroscopy, electrochemical studies and transmission electron microscopy. The reaction of viologen pendant pyrrole with colloidal gold solution was indicated by a shift in the plasmon peak due to the formation of gold nanoparticles/viologen aggregate. The reaction between them was further confirmed from cyclic voltammetry and electron microscopic studies. The methodology employed in this study can be utilized to design novel building blocks of polypyrrole-derived viologen pendant gold nanoparticles containing nanocomposites on electrode surfaces for various sensor and electrocatalytic applications.
