CSIC ORCID ; López, María Francisca CSIC ORCID | Fecha de publicación: | 31-jul-2017 | Editor: | Royal Society of Chemistry (UK) | Citación: | Physical Chemistry Chemical Physics 19: 22454-22461 (2017) | Resumen: | New nanoarchitectures can be built from polycyclic aromatic hydrocarbons (PAHs) by exploiting the capability of some metal surfaces for inducing cyclodehydrogenation reactions. This bottom-up approach allows the formation of nanostructures with a different dimensionality from the same precursor as a consequence of the diffusion and coupling of the PAHs adsorbed on the surface. In this work we present a thorough study, by means of a combination of X-ray photoemission spectroscopy, near-edge X-ray absorption fine structure and scanning tunneling microscopy with first principle calculations of the structural and chemical transformations undergone by pyridyl-substituted dibenzo[5]helicene on three coinage surfaces, namely Cu(110), Cu(111) and Au(111). Upon annealing, on-surface chemical reactions are promoted affecting the adsorbate/substrate and the molecule/molecule interactions. This thermally induced process favours the transformation from diffusing isolated molecules to polymeric nanographene chains and finally to N-doped graphene. | Versión del editor: | http://dx.doi.org/10.1039/C7CP03955G | URI: | http://hdl.handle.net/10261/164246 | DOI: | 10.1039/C7CP03955G | ISSN: | 1463-9076 | E-ISSN: | 1463-9084 |
