  • Recent advances in the synthesis of graphene fragments that possess unpaired π-electrons and display high-spin ground states have unlocked possibilities to explore exotic physical phenomena related to magnetism. Here, the authors demonstrate the magnetic bistability of a diradical nanographene that allows direct spin manipulation at the single-molecule level.

  • Current photodynamic therapy photosensitizers require oxygen; however, tumours are often hypoxic. Now, an organoiridium complex with an unusually high redox potential, which is effective in normoxia and hypoxia, has been developed. The organoiridium complex kills cancer cells by an immunogenic apoptotic mechanism involving efficient photocatalytic oxidation of NADH to NAD radicals, and reduction of cytochrome c.

  • Self-assembly in the formation of two dimensional materials typically relies upon strong, directional interactions instead of covalent bonds but control over less directional forces remains challenging. Here, the authors show the process of shape-assisted self-assembly to be consistent across a range of derivatives that highlights the restriction of rotational motion.

  • Molecular catalysts can be made more practical by anchoring them onto electrode surfaces, but such systems are less stable than standard heterogeneous electrocatalysts. Now, supramolecular hosts bound to electrode surfaces have enabled the immobilization of molecular electrocatalysts through host–guest interactions. Desorbed or degraded guest molecules can be replaced with fresh guest molecules, extending their lifetimes.

  • Photosensitizers that  are stable in biological conditions with absorption in the biological spectral window are needed for photodynamic therapy. Here, the authors report on the development of a Ruthenium complex for 1 and 2-photon therapy to address these issues and demonstrate application in vivo.

  • The ham gene cluster in Burkholderia cenocepacia H111 produces two compounds: the signalling molecule valdiazen as racemate and the antifungal fragin in enantiopure form. Here, the authors demonstrate that the stereodivergence is based on the heterocyclic intermediate dihydrosydnone N-oxide, with both non-enzymatic racemization and enzyme-mediated dynamic kinetic resolution occurring in parallel.
