Tunable Current Rectification Through a Designer Graphene Nanoribbon
Niklas Friedrich, Jingcheng Li, Iago Pozo +2
Unimolecular current rectifiers are fundamental building blocks in organic electronics. Rectifying behavior has been identified in numerous organic systems due to electron-hole asy…
Emergence of π-Magnetism in Fused Aza-Triangulenes: Symmetry and Charge Transfer Effects
Jan Patrick Calupitan, Alejandro Berdonces-Layunta, Fernando Aguilar-Galindo +6
On-surface synthesis has paved the way towards the fabrication and characterization of conjugated carbon-based molecular materials that exhibit π-magnetism such as triangulenes. Az…
On-Surface Synthesis and Characterization of a High-Spin Aza-[5]-Triangulene
Manuel Vilas-Varela, Francisco Romero-Lara, Alessio Vegliante +13
Triangulenes are open-shell triangular graphene flakes with total spin increasing with their size. In the last years, on-surface-synthesis strategies have permitted fabricating and…
Bistability between -diradical open-shell and closed-shell states in indeno[1,2-a]fluorene
Shantanu Mishra, Manuel Vilas-Varela, Leonard-Alexander Lieske +7
Indenofluorenes are non-benzenoid conjugated hydrocarbons that have received great interest owing to their unusual electronic structure and potential applications in non-linear opt…
Planar bridging an atomically precise surface trench with a single molecular wire on an Au(111) surface
Umamahesh Thupakula, Xavier Bouju, Jesús Castro-Esteban +3
In a bridge configuration, a single graphene nanoribbon (GNR) is positioned with a picometer precision over a trench in between two monoatomic steps on an Au(111) surface. This GNR…
Selectivity in single-molecule reactions by tip-induced redox chemistry
Florian Albrecht, Shadi Fatayer, Iago Pozo +4
Controlling selectivity of reactions is a quest in chemistry. Here, we demonstrate reversible and selective bond formation and dissociation promoted by tip-induced reduction-oxidat…
Addressing electron spins embedded in metallic graphene nanoribbons
Niklas Friedrich, Rodrigo E. Menchon, Iago Pozo +7
Spin-hosting graphene nanostructures are promising metal-free systems for elementary quantum spintronic devices. Conventionally, spins are protected from quenching by electronic ba…
Non-benzenoid high-spin polycyclic hydrocarbons generated by atom manipulation
Shantanu Mishra, Shadi Fatayer, Saleta Fernandez +3
We report the on-surface synthesis of a non-benzenoid triradical through dehydrogenation of truxene (C27H18) on coinage metal and insulator surfaces. Voltage pulses applied via the…
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…
