Resumen:
Surface topography and work function maps were simultaneously obtained for carbon surfaces modified by a dendritic molecule: 3,5-Bis (3,5-dinitrobenzoylamino) benzoic acid (D-NO2). The dendrons were spontaneously assembled onto highly ordered pyrolytic graphite (HOPG) samples, exhibiting an increase in the surface potential. This fact is consistent with the incorporation of an electron-acceptor functional group that remains electroactive onto the surface.
