      Gómez González, Jacobo; Peña Gil, Diego; Barka, Ghofrane; Sciortino, Giuseppe; Maréchal, Jean-Didier; Vázquez López, Miguel; Vázquez Sentís, Marco Eugenio (Frontiers Media, 2018)
      We propose that peptides are highly versatile platforms for the precise design of supramolecular metal architectures, and particularly, for the controlled assembly of helicates. In this context, we show that the bacteriophage ...
    • Exploring a route to cyclic acenes by on-surface synthesis 

      Schulz, Fabian; García Melo, Fátima; Kaisser, Katharina; Pérez Meirás, María Dolores; Guitián Rivera, Enrique Carlos; Gross, Leo; Peña Gil, Diego (Willey, 2019)
      A route to generate cyclacenes by on-surface synthesis is explored. We started by synthesizing two tetraepoxycyclacenes by sequences of Diels–Alder cycloadditions. Subsequently, these molecules were deposited onto ...
    • Intramolecular Coupling of Terminal Alkynes by Atom Manipulation 

      Albrecht, Florian; Rey Vieites, Dulce María; Fatayer, Shadi; Schulz, Fabian; Pérez Meirás, María Dolores; Peña Gil, Diego; Gross, Leo (Wiley, 2020)
      Glaser‐like coupling of terminal alkynes by thermal activation is extensively used in on‐surface chemistry. Here we demonstrate an intramolecular version of this reaction performed by atom manipulation. We used voltage ...
    • Microwave-induced covalent functionalization of few-layer graphene with arynes under solvent-free conditions 

      Sulleiro, M. V.; Quiroga Fernández, Sabela; Peña Gil, Diego; Pérez Meirás, María Dolores; Guitián Rivera, Enrique Carlos; Criado Fernández, Alejandro; Prato, Maurizio (Royal Society of Chemistry, 2018)
      A non-conventional modification of exfoliated few-layer graphene (FLG) with different arynes under microwave (MW) irradiation and solvent-free conditions is reported. The described approach allows reaching fast, efficient ...
    • Single spin localization and manipulation in graphene open-shell nanostructures 

      Li, Jingcheng; Sanz, Sofia; Choi, Deung Jang; Corso, Martina; Peña Gil, Diego; Frederiksen, Thomas; Pascual, Jose Ignacio (Nature publishing group, 2019)
      Turning graphene magnetic is a promising challenge to make it an active material for spintronics. Predictions state that graphene structures with specific shapes can spontaneously develop magnetism driven by Coulomb repulsion ...
    • Site-selective reversible Diels–Alder reaction between a biphenylene-based polyarene and a semiconductor surface 

      Godlewski, Szymon; Engelund, Mads; Peña Gil, Diego; Zuzak, Rafał; Kawai, Hiroyo; Kolmer, Marek; Caeiro Rodríguez, Jorge; Guitián Rivera, Enrique; Vollhardt, K. Peter C.; Sánchez-Portal, Daniel; Szymonski, Marek; Pérez Meirás, María Dolores (Royal Society of Chemistry, 2018-04-28)
      Understanding the mechanisms involved in the covalent attachment of organic molecules to surfaces is a major challenge for nanotechnology and surface science. On the basis of classical organic chemistry mechanistic ...
    • Stabilizing Edge Fluorination in Graphene Nanoribbons 

      Panighel, Mirco; Quiroga Fernández, Sabela; Brandimarte, Pedro; Moreno, Cesar; García Lekue, Aran; Vilas Varela, Manuel; Rey Vieites, Dulce María; Sauthier, Guillaume; Ceballos, Gustavo; Peña Gil, Diego; Mugarza, Aitor (American Chemical Society, 2020)
      The on-surface synthesis of edge-functionalized graphene nanoribbons (GNRs) is challenged by the stability of the functional groups throughout the thermal reaction steps of the synthetic pathway. Edge fluorination is a ...
    • Straightforward Synthesis of Novel Acene-Based Aryne Precursors 

      Rodríguez-Lojo, Diego; Peña Gil, Diego; Pérez Meirás, María Dolores; Guitián Rivera, Enrique (Thieme Publishing, 2015-06-11)
      Large polycyclic o-(trimethylsilyl)aryl triflates are easily obtained by reaction of commercially available bisaryne precursors with cyclopentadienones. The transformation involves controlled generation of one of the aryne ...

      Antiaromatic and open-shell molecules are attractive because of their distinct electronic and magnetic behaviour. However, their increased reactivity creates a challenge for probing their properties. Here, we describe the ...
    • Survival of spin state in magnetic porphyrins contacted by graphene nanoribbons 

      Li, Jingcheng; Merino Díez, Nestor; Carbonell Sanromà, Eduard; Vilas Varela, Manuel; Oteyza, Dimas G. de; Peña Gil, Diego; Corso, Martina; Pascual, Jose Ignacio (American Association for the Advancement of Science (AAAS), 2018)
