  • Ever-increasing society needs have made thermosets crucial, but their recycling poses considerable challenges. Dynamic covalent chemistry (DCC) offers a solution, and industry is ready for its implementation. On the basis of market proximity, three DCC-based strategies are proposed for stimulating industrial uptake of DCC-thermosets.

  • Weak force-activated covalent bonds as crosslink points can increase mechanical strength and ductility in polymers but the bonds, once broken, cannot be reformed in real time under ambient conditions leading to irreversible damage. Here, the authors demonstrate that triazolinedione (TAD)-indole adducts acting as crosslink points enable materials to display already at ambient temperature reversible stress-responsiveness in real time.

  • Chemical topology is important in bond-forming reactions, but understanding the relationship between them is challenging. Here, the authors report a study considering photo-induced cyclisations for a series of monodisperse macromolecules with defined spacers and apply their findings to 3D printing.

  • Vitrimers are malleable networks based on thermally triggered associative exchange reactions and thus can be used for processing, recycling and self-healing materials. Here the authors show how acids and bases affect the exchange kinetics and in turn rationalize these effects mechanistically.

  • Sequence-defined macromolecules consist of a defined chain length and topology and can be used in applications such as antibiotics and data storage. Here the authors developed two algorithms to encode text fragments and QR codes as a collection of oligomers and to reconstruct the original data.

  • Macromolecular functionalization and linking are often facilitated by using ‘click’ chemistries. Now, triazolinediones have been used in ultrafast click reactions under additive-free, ambient conditions for polymer conjugation. Clicking to indoles gives an adduct that is dynamic at elevated temperatures, which produces properties such as polymer-network healing, reshaping and recycling.

  • The ability to switch between thermally and photochemically activated reaction channels with an external stimulus constitutes a key frontier within the realm of chemical reaction control. Here, the authors describe how the thermal reactivity of molecules can completely be switched off by visible light to provide UV light-induced selectivity of the reaction outcome.
