From Solution to Surface: Persistence of the Diradical Character of a Diindenoanthracene Derivative on a Metallic Substrate
Jeremy Hieulle, Carlos Garcia Fernandez, Niklas Friedrich +7
Organic diradicals are envisioned as elementary building blocks for designing a new generation of spintronic devices and have been used in constructing prototypical field effect tr…
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…
Tuning the Spin Interaction in Non-planar Organic Diradicals Through Mechanical Manipulation
Alessio Vegliante, Saleta Fernandez, Ricardo Ortiz +12
Open-shell polycyclic aromatic hydrocarbons (PAHs) represent promising building blocks for carbon-based functional magnetic materials. Their magnetic properties stem from the prese…
Fluorescent single-molecule STM probe
Niklas Friedrich, Anna Roslawska, Xabier Arrieta +7
The plasmonic tip of a scanning tunnelling microscope (STM) is functionalized with a single fluorescent molecule and is scanned on a plasmonic substrate. The tunneling current flow…
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…
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…
Aza-Triangulene: On-Surface Synthesis, Electronic and Magnetic Properties
Tao Wang, Alejandro Berdonces-Layunta, Niklas Friedrich +7
Nitrogen heteroatom doping into a triangulene molecule allows tuning its magnetic state. However, the synthesis of the nitrogen-doped triangulene (aza-triangulene) has been challen…
On-surface synthesis and collective spin excitations of a triangulene-based nanostar
Jeremy Hieulle, Silvia Castro, Niklas Friedrich +8
Triangulene nanographenes are open-shell molecules with predicted high spin state due to the frustration of their conjugated network. Their long-sought synthesis became recently po…
Magnetism of topological boundary states induced by boron substitution in graphene nanoribbons
Niklas Friedrich, Pedro Brandimarte, Jingcheng Li +8
Graphene nanoribbons (GNRs), low-dimensional platforms for carbon-based electronics, show the promising perspective to also incorporate spin polarization in their conjugated electr…
Uncovering the Triplet Ground State of Triangular Graphene Nanoflakes Engineered with Atomic Precision on a Metal Surface
Jingcheng Li, Sofia Sanz, Jesus Castro-Esteban +5
Graphene can develop large magnetic moments in custom crafted open-shell nanostructures such as triangulene, a triangular piece of graphene with zigzag edges. Current methods of en…
Electrically addressing the spin of a magnetic porphyrin through covalently connected graphene electrodes
Jingcheng Li, Niklas Friedrich, Nestor Merino +4
We report on the fabrication and transport characterization of atomically-precise single molecule devices consisting of a magnetic porphyrin covalently wired by graphene nanoribbon…
