Latent catalysis in olefin metathesis has revolutionized polymer chemistry, enabling significant advancements in polymer properties and additive manufacturing. Traditionally, latency has been achieved by modifying the catalyst, but recent breakthroughs demonstrate that the monomer itself can be engineered for controlled activation. By incorporating photoswitchable olefins—specifically, quadricyclane–norbornadiene systems—researchers have developed monomers that remain inert until exposed to specific wavelengths of light. This photoswitchable behavior allows for precise spatial and temporal control over polymerization, opening new possibilities for advanced materials, responsive coatings, and high-resolution 3D printing. The ability to trigger polymerization on demand not only enhances process efficiency but also paves the way for innovative applications in smart materials and nanotechnology. Read the source »
