  • Chirality plays a critical role in the structure and function of natural and synthetic polymers, impacting their properties. Here, the authors achieve single-chain chemical analysis to unravel the emergence of different forms of chirality from small molecules to their resulting polymers and supramolecular assemblies.

  • Precise control over both sequence and chirality remains a challenge in polymer chemistry. Here sulfur–fluoride exchange and sulfur–phenolate exchange reactions are used to create chiral oligosulfonimidates with tunable sulfur-centred chirality. This strategy enables precise three-dimensional structural control over oligomers and polymers, marking a step towards fully nature-mimicking macromolecules.

  • Sulfur(vi) fluoride exchange (SuFEx)—a type of click chemistry that generates SVI-centred covalent linkages—has previously been used for polymer synthesis. Now, modular SuFEx polymerization using SOF4 has been used to generate helical polymers. Unlike previous examples of SuFEx polymerization, the backbone retains SVI–F motifs and therefore is able to undergo further SuFEx click reactions, enabling facile and efficient post-polymerization modification.

  • Beekman et al. investigate whether low molecular weight organosilicon compounds leaching out of commonly used biological laboratory materials and household items can interact with molecules found in cellular membranes. The results suggest this is a passive process by physicochemical forces rather than active uptake.
