Resumo

The construction of molecular nanostructures with tunable topological structures is a challenge in molecular engineering. We report a novel organic pi-conjugated chromophore obtained by the electropolymerization of Bismarck Brown Y (4,40-{[}1,3-phenylenedi(E)-2,1diazenediyl]di(1,3-benzenediamine)), with important potential applications in optical and electrochemical materials. The study comprises evidence regarding the redox transitions during the electropolymerization process by potential cycling and information regarding the physico-chemical properties of the polymerized film by UV-Vis spectroscopy, electrochemical impedance spectroscopy and scanning electron microscopy. The spectral study indicates a pi-conjugated planar structure with predominance of the cis isomer. The polymer with diverse molecular conformation paves the way to fabricate molecular miniature devices with various desired functionalities. (AU)
