  • Bis(arylimino)acenaphthene ligands were recognized as robust scaffolds for metal complexes decades ago, but their redox non-innocence as well as their potential to mediate electro- or photo-catalysis remain subjects of active research. Here, the authors review the synthesis and properties of these poly-aromatic diimine ligands complexed to nominally redox-innocent p-block elements.

  • While the bulk structures of metal–organic frameworks can be solved by diffraction-based techniques, characterization of their local structures has been lacking. Here the authors review recent advances in (scanning) transmission electron microscopy that have made it possible to probe the local structures of MOFs at atomic resolution.

  • In celebration of International Women’s Day, on 6 March 2020 the University of Nottingham hosted its second Women in Chemistry conference. Or, as branded by a security guard at the host building, a ‘chemical ladies’ meeting’. Victoria Richards recounts the event and shares key take-home messages from the speakers.

  • Three-dimensional covalent organic frameworks are attractive functional materials, although there are fewer examples than their two-dimensional counterparts. Here, the authors review the synthetic approaches yielding these compounds, and highlight key challenges facing researchers in the field.
