On‐Surface Debromination of 2,3‐Bis (dibromomethyl)‐ and 2,3‐Bis (bromomethyl) naphthalene: Dimerization or Polymerization?
Abstract: We describe the on‐surface dehalogenative homocoupling of benzylic bromides, namely bis‐bromomethyl‐ and bis‐gem‐(dibromomethyl) naphthalene as a potential route to either hydrocarbon dimers or conjugated polymers on Au (111). While bis‐gem‐(dibromomethyl) naphthalene affords different dimers with naphthocyclobutadiene as the key intermediate, bis‐bromomethyl naphthalene furnishes a poly (o‐naphthylene vinylidene) as a non‐conjugated polymer which undergoes dehydrogenation toward its conjugated derivative poly (o‐naphthylene vinylene) upon mild annealing. A combination of scanning tunneling microscopy, non‐contact atomic force microscopy and density functional theory calculations provides deep insights into the prevailing mechanisms.
