  • Interactions between anions and π-systems are possible with electron-poor aromatic surfaces. Here the authors show that anion-π interactions can stabilize enolates—lowering the pKa of the carbonyl compound by almost two units—and likewise accelerate the addition of enolates to electrophiles.

  • The propensity of guanine and its derivatives to assemble into guanine quartets makes them a privileged tool in the design of functional supramolecular assemblies. This Review describes the production of such functional suprastructures and their applications in nanotechnology, soft matter and chemical biology.

  • Synthetic vesicles with membranes made from amphiphiles that are fluorescence acceptors encapsulate donor molecules in their cores, and emit different proportions of red, blue and green light depending on pH. The balance of these coloured emissions at pH 9 results in white fluorescence.

  • The transport of anions across bilayer membranes is achieved by ion channel proteins, but some small molecules are also able to mediate transmembrane movement of anions. In this study, the halogen bonding of small perfluorinated molecules is shown to allow the transmembrane movement of anions.

  • For quadrupole moments up to +39 Buckinghams, increasing π-acidity of aromatic surfaces is shown to cause tighter anion binding in tandem mass spectrometry experiments, higher binding energies in molecular models, stronger charge-transfer absorption bands, and increasingly effective and selective anion transport across lipid-bilayer membranes.

  • The self-sorting of molecular building blocks should allow 2D surface patterns to be transcribed into 3D functional materials. Here, a non-empirical approach to the templated synthesis of supramolecular architectures on surfaces is reported, starting with a theoretical model and followed by comprehensive experimental validation, including direct evidence for functional relevance of the produced materials.

  • Artificial enzymes can be used to elicit reactions in cells. Here, the authors developed such an artificial catalyst combined with a genetic switch, and showed that it was readily taken up by human cells and able to kick off a reaction cascade resulting in the biosynthesis of the desired product.

  • Osmotic compensation by electroneutral ion transport buffers TORC1-mediated changes in the cytosolic proteome, and maintains intracellular homeostasis and cell volume over the circadian cycle. Here, the authors find such ion content changes drive daily rhythms in cardiomyocyte electrical activity.

  • Lipid membranes—which separate cells and organelles from their environment—experience tension during various cell processes; however, measuring membrane tension is notoriously difficult. Now, a new fluorescent, mechanosensitive membrane probe called FliptR has been developed. FliptR enables simple, direct membrane tension measurements in cellular and artificial membranes.

  • High-speed atomic force imaging allows for the visualisation of molecular‐level activity in real-time. Here, the authors use HS-AFM to image the activity of an antimicrobial peptide on a membrane and are able to detect previously unknown molecular mechanisms behind its action.
