On-surface synthesis of a doubly anti-aromatic carbon allotrope

The carbon allotrope cyclo[16]carbon has been synthesized using on-surface chemistry and characterized with scanning tunnelling microscopy and atomic force microscopy, revealing orbital densities and bond-length alternation, which show it to be doubly anti-aromatic.

Comparison of dual therapies for hypertension treatment in India: a randomized clinical trial

To address an evidence gap for the efficacy of hypertension therapy using dual drug combinations in patients of South Asian origin, a randomized clinical trial conducted in India found that three types of dual drug combinations, each administered in a single pill, had similarly large effects on reducing blood pressure.

Large magnetic exchange coupling in rhombus-shaped nanographenes with zigzag periphery

Open-shell nanographenes are promising for quantum technologies, but their magnetic stability has remained limited by weak exchange coupling. Now, two large rhombus-shaped nanographenes with zigzag peripheries, one with 48 carbon atoms and the other with 70, have been synthesized on gold and copper surfaces. The 70-carbon compound exhibits a large magnetic exchange coupling exceeding 100 meV.

Bistability between π-diradical open-shell and closed-shell states in indeno[1,2-a]fluorene

Switching the magnetic state of a polycyclic conjugated hydrocarbon in a reversible and controlled manner is challenging. Now, by means of single-molecule scanning probe microscopy, an indenofluorene isomer on ultrathin NaCl films has been shown to adopt both open- and closed-shell states. Furthermore, bidirectional switching between the two states is achieved by changing the adsorption site of the molecule.

Twisted bilayer zigzag-graphene nanoribbon junctions with tunable edge states

Twisted 2D materials have recently emerged as a controllable quantum simulator platform. Here, the authors apply the same approach to tune the edge states of zigzag graphene nanoribbons, showing a unique degree of freedom represented by the lateral stacking offset of the 1D nanostructures.

On-surface light-induced generation of higher acenes and elucidation of their open-shell character

The synthesis of large acenes via traditional solution-chemistry routes is hindered by their poor solubility and high reactivity under ambient conditions. Here, the authors demonstrate the on-surface formation of large acenes, via visible-light-induced photo-dissociation of α-bisdiketone molecular precursors on an Au(111) substrate.

On-surface synthesis of a nitrogen-embedded buckybowl with inverse Stone–Thrower–Wales topology

Heteroatom doping of buckybowls is a viable route to tune their intrinsic physico-chemical properties, but their synthesis remains challenging. Here, the authors report on a combined in-solution and on-surface synthetic strategy towards the fabrication of a buckybowl containing two fused nitrogen-doped pentagonal rings.

Topological frustration induces unconventional magnetism in a nanographene

Topological frustration in the π-electron network of the polycyclic aromatic hydrocarbon C₃₈H₁₈ yields unpaired electrons and a magnetically non-trivial ground state. Here, the authors synthesize this molecule, known as Clar’s goblet, on Au(111) and characterize the antiferromagnetic ground state with scanning tunnelling microscopy.
