Plasmonic Chirality Meets Reactivity: Challenges and Opportunities

The unique optoelectronic features associated with plasmonic nanomaterials in a broad energy range of the electromagnetic spectrum have the potential to overcome the current limitations in the development of heterogeneous photocatalytic systems with enantioselective capabilities. Recent advancements in creating plasmonic structures with strong chiroptical features have already enabled asymmetric recognition of molecular substrates or even polarization-sensitive chemical reactivity under visible and near-infrared irradiation. Nevertheless, important developments need to be achieved to attain real enantioselective reactivity solely driven by plasmons. This Perspective discusses current trends in the formation of chiral plasmonic materials and their application as photocatalysts to achieve stereocontrol in photochemical reactions. We summarize the challenges in this field and offer insight into future opportunities that could enhance the effectiveness of these innovative systems.
