  • Latent catalysis in olefin metathesis has seen great progress over the years, leading to key advances in the properties of polymers and 3D printing technologies. Now it is shown that the latency mechanism can be extended to the monomer through quadricyclane–norbornadiene interconversion, expanding the tools available to this field.

  • Current strategies for photoinduced olefin metathesis lack wavelength tunability. Now, plasmonic nanoparticles have been used to activate latent ruthenium catalysts, enabling light-induced olefin metathesis in the infrared range with several advantages when compared with conventional heating. Implementing this approach in ring-opening metathesis polymerization resulted in photoresponsive polymer–nanoparticle composites with enhanced mechanical properties.

  • Artificial metalloenzymes (ArMs) often have sensitive metal centers. Here the authors enhance ArM performance by inducing liquid–liquid phase separation in Escherichia coli, creating protective compartments. This strategy boosts ArM loading, stabilizes activity and enables in vivo applications.

  • Frontal ring-opening metathesis polymerization (FROMP) is a promising energy-efficient approach to fabricate polymeric materials but the characteristic properties of the front are currently controlled primarily by varying the resin composition or the environmental conditions. Here, the authors present an approach to control FROMP of dicyclopentadiene using photochemical methods.
