Parity-dependent coupling of molecular spin chains to a superconductor
Katerina Vaxevani, Jon Ortuzar, Stefano Trivini +6
Topological order can fractionalize the quantum numbers of the underlying particles. A paradigmatic example is the spin-1/2 states at the edges of an antiferromagnetic integer-spin…
Selectivity in tip-induced skeletal editing via heteroatom substitution
Shantanu Mishra, Rasmus Svensson, Valentina Malave +5
Skeletal editing enables precise structural modifications of molecules at late stages of a synthetic sequence, with applications in drug discovery and materials science. We recentl…
Topological Engineering of a Frustrated Antiferromagnetic Triradical in Aza-Triangulene Architectures
Francisco Romero-Lara, Manuel Vilas-Varela, Manish Kumar +16
Open-shell nanographenes provide a versatile platform to host unconventional magnetic states within their π-conjugated networks. Particularly appealing are graphene architectures t…
Skeletal editing by tip-induced chemistry
Shantanu Mishra, Valentina Malave, Rasmus Svensson +4
Skeletal editing of cyclic molecules has garnered considerable attention in the context of drug discovery and green chemistry, with notable examples in solution-phase synthesis. He…
A Single-Molecule Quantum Heat Engine
Serhii Volosheniuk, Riccardo Conte, Eugenia Pyurbeeva +6
Particle-exchange heat engines operate without moving parts or time-dependent driving, relying solely on static energy-selective transport. Here, we realize a particle-exchange qua…
Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet
Leonard Edens, Francisco Romero Lara, Trisha Sai +5
Tailor-made graphene nanostructures can exhibit symmetry-protected topological boundary states that host localized spin- moments. However, one frequently observes charge trans…
On-surface Synthesis of a Ferromagnetic Molecular Spin Trimer
Alessio Vegliante, Manuel Vilas-Varela, Ricardo Ortiz +12
Triangulenes are prototypical examples of open-shell nanographenes. Their magnetic properties, arising from the presence of unpaired electrons, can be extensively tuned by modi…
Synthesis and characterization of a -extended Clar's goblet
Shantanu Mishra, Manuel Vilas-Varela, Igor Rončević +4
Concealed non-Kekulé polybenzenoid hydrocarbons have no sublattice imbalance yet cannot be assigned a classical Kekulé structure, leading to an open-shell ground state with potenti…
A Route Toward the On-Surface Synthesis of Organic Ferromagnetic Quantum Spin Chains
Fabian Paschke, Ricardo Ortiz, Shantanu Mishra +5
Engineering sublattice imbalance is an intuitive way to induce high-spin ground states in bipartite polycyclic conjugated hydrocarbons (PCHs). Such high-spin molecules can be emplo…
Systematic Modulation of Charge and Spin in Graphene Nanoribbons on MgO
Amelia Domínguez-Celorrio, Leonard Edens, Sofía Sanz +7
Graphene nanostructures can be engineered with atomic precision to display customized electronic states with application in spintronics or quantum technologies. In order to take ad…
Observation of SOMO-HOMO inversion in a polycyclic conjugated hydrocarbon
Shantanu Mishra, Manuel Vilas-Varela, Shadi Fatayer +3
We report the generation of a non-benzenoid polycyclic conjugated hydrocarbon, which consists of a biphenyl moiety substituted by indenyl units at the 4,4' positions, on ultra-thin…
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…
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…
Intramolecular coupling of terminal alkynes by atom manipulation
Florian Albrecht, Dulce Rey, Shadi Fatayer +4
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…
