Summary:On-surface synthesis of a polyphenylene vinylene oligomer via reductive coupling of a terephthalaldehyde derivative on Au(111) is reported. Scanning tunneling microscopy and photoelectron spectroscopy experiments confirmed oxygen dissociation and its desorption from the surface. Density functional theory calculations provided a reasonable reaction mechanism involving reactive sites on the substrate. A reductive process allows to covalently couple aldehydes on a Au(111) surface. While oxygen desorbs completely during the reaction, a strongly interlinked polyphenylene vinylene derivative is formed, remaining weakly adsorbed on the surface.
