Order from a mess: the growth of 5-armchair graphene nanoribbons
Alejandro Berdonces-Layunta, Fabian Schulz, Fernando Aguilar-Galindo +6
The advent of on-surface chemistry under vacuum has vastly increased our capabilities to synthesize carbon-nanomaterials with atomic precision. Among the types of target structures…
Circumventing the Stability Problems of Graphene Nanoribbon Zigzag Edges
James Lawrence, Alejandro Berdonces-Layunta, Shayan Edalatmanesh +7
Carbon nanostructures with zigzag edges exhibit unique properties with exciting potential applications. Such nanostructures are generally synthesized under vacuum because their zig…
Steering alkyne homocoupling with on-surface synthesized catalysts
Mohammed S. G. Mohammed, Luciano Colazzo, Aurelio Gallardo +3
We report a multi-step on-surface synthesis strategy. The first step consists in the surface-supported synthesis of metal-organic complexes, which are subsequently used as catalyst…
Transferring Axial Molecular Chirality Through a Sequence of On-Surface Reactions
Néstor Merino-Díez, Mohammed S. G. Mohammed, Jesús Castro-Esteban +6
Fine management of chiral processes on solid surfaces has progressed over the years, yet still faces the need for the controlled and selective production of advanced chiral materia…
Controlling the stereospecific bonding motif of Au-thiolate links
Luciano Colazzo, Mohammed S. G. Mohammed, Aurelio Gallardo +4
Organosulfur compounds at the interface to noble metals have proved over the last decades to be extremely versatile systems for both fundamental and applied research. However, the…
Electronic Decoupling of Polyacenes from the Underlying Metal Substrate by sp3 Carbon Atoms
Mohammed S. G. Mohammed, Luciano Colazzo, Roberto Robles +4
We report on the effect of sp3 hybridized carbon atoms in acene derivatives adsorbed on metal surfaces, namely decoupling the molecules from the supporting substrates. In particula…
Electronic structure tunability by periodic meta-ligand spacing in one-dimensional organic semiconductors
Ignacio Piquero-Zulaica, Aran Garcia-Lekue, Luciano Colazzo +7
Designing molecular organic semiconductors with distinct frontier orbitals is key for the development of devices with desirable properties. Generating defined organic nanostructure…
Hierarchy in the halogen activation during surface-promoted Ullmann coupling
Néstor Merino-Díez, Alejandro Pérez Paz, Jingcheng Li +9
Within the collection of surface-supported reactions currently accessible for the production of extended molecular nanostructures under ultra-high vacuum, Ullmann coupling has been…
Probing the magnetism of topological end-states in 5-armchair graphene nanoribbons
James Lawrence, Pedro Brandimarte, Alejandro Berdonces +5
We extensively characterize the electronic structure of ultra-narrow graphene nanoribbons (GNRs) with armchair edges and zig-zag termini that have 5 carbon atoms across their width…
On-Surface Synthesis of Heptacene on Ag(001) from Brominated and Non-Brominated Tetrahydroheptacene Precursors
Luciano Colazzo, Mohammed S. G. Mohammed, Ruth Dorel +6
Achieving the Ag(001)-supported synthesis of heptacene from two related reactants reveals the effect of the presence of Br atoms on the reaction process. The properties of reactant…
