  • 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.

  • Introduced here is a light-induced MOF synthesis, enabled by plasmonic nanoparticles. The method, proven to be rapid and efficient, can also promote the formation of a nanoparticle-MOF composite, imparting photothermal properties to the new material.

  • 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.

  • Photothermal solution heating with nanoscale heat sources is an efficient alternative to conventional heating methods. Here, the authors use silica-encapsulated gold nanoparticles to drive the colloidal synthesis of iron oxide, silver, and palladium nanoparticles at lower temperatures.
