Quantum anomalous Hall (QAH) insulators transport charge without resistance along topologically protected chiral 1D edge states. Yet, in magnetic topological to date, protection is far from robust, with zero-magnetic field QAH effect only realized at temperatures an order of magnitude below the Néel temperature T
Low dimensional carbon-based materials are interesting because they can show intrinsic $\pi$-magnetism associated to p-electrons residing in specific open-shell configurations. Consequently, during the last years there have been impressive advances field combining indirect experimental fingerprints of localized magnetic moments with theoretical models. In spite that, a characterization their spatial- and energy-resolved spin-moment has so far remained elusive. To obtain this information, we...
The synthesis of novel organic prototypes combining different functionalities is key to achieve operational elements for applications in electronics. Here we set the stage towards individually addressable magneto-optical transducers by on-surface optically active manganese-phthalocyanine derivatives (MnPc) obtained directly on a metallic substrate. We created these 2D nanostructures under ultra-high vacuum conditions with atomic precision starting from simple phthalonitrile precursor...
Graphene nanostructures are a promising platform for engineering electronic states with tailored magnetic and quantum properties. Synthesis strategies on metallic substrates have made it possible to manufacture atomically precise nanographenes controlled size, shape edge geometry. In these nanographenes, finite spin moment can arise as result of many-body interactions in molecular orbitals $\pi$-conjugated character subject strong spatial confinement, example at the zig-zag edges. However,...
Two-dimensional molecular assemblies on surfaces have opened a way to design and control chirality, featuring promising electronic chemical properties that depend the local handedness of layer. Yet, mechanisms leading spontaneous chiral resolution are not fully understood at every reaction stage. Here, starting from achiral 10-bromoanthracene-9-boronic acid as precursor, we demonstrate enantiomeric induction in products during stage covalent bonding, stemming competing point symmetries...
The synthesis and photovoltaic study of five dyes based on 4H-pyranylidene moiety as donor is reported. A thiophene unit conjugated with/without an ethynyl bond acts the π-relay benzoic acid anchor group a trifluoromethyl group. Their electrochemical optical properties are analyzed by using joint experimental theoretical approach. presence leads to enhancement molar extinction coefficient, being slightly when hexyl chain introduced in ring, but does not modify oxidation potential. For...
