“…Referred to plasmon-induced reactions in nanoconfined space, the strong coupling of molecules with plasmon frequency in plasmonic nanocavities (such as NPs on mirrors) offers interesting possibilities to manipulate chemical bond evolution and modify photochemistry. 79 In 2016, Baumberg and coworkers demonstrated that a plasmonic nanocavity containing an MB dye molecule can result in strong single-molecule coupling between the emitter and the plasmon (Figure 9e). 80 Soon after, Feist et al showed that strong coupling of organic molecules to a confined light mode can be used to strongly suppress photoisomerization.…”

Plasmonic catalysis is an ever-growing field in which chemical reactions are enabled by visible light excitation. The plasmonic effects provide a unique reaction environment, which can greatly affect chemical reaction processes. On the basis of extensive research on plasmon-induced chemical reactions, we focus on the fundamentals of plasmon-mediated catalytic selectivity and summarize recent advances and emerging opportunities in selective chemical bond evolution in this perspective. Taking representative reactions as examples, the unique feature and advantage of surface plasmons in modulating reaction selectivity are deciphered from the perspective of the three elementary steps: adsorption of reactants, activation of adsorbates, and desorption of products. In addition, nanoconfined plasmon-induced spatially selective reactions are also included. This perspective informs insights and opportunities for rationally engineering plasmonic catalytic systems toward purposeful solar energy utilization.

“…If the exchange process is faster than other dissipation rates, it results in the formation of new hybrid states-polaritonic states separated by Rabi splitting energy. [1][2][3] This process becomes more intriguing if an Avogadro number of molecules are collectively coupled to the cavity mode. Collective coupling results in large Rabi splitting energy that can reshuffle the chemical and physical properties of the associated system.…”

Strong light‐matter interaction is emerging as an exciting tool for controlling chemical reactions. Here, we demonstrate an L‐proline‐catalyzed direct asymmetric Aldol reaction under vibrational strong coupling. Both the reactants (4‐nitrobenzaldehyde and acetone) carbonyl bands are coupled to an infrared photon and react in the presence of L‐proline. The reaction mixture is eluted from the cavity, and the conversion yields and enantiomeric excess are quantified using NMR and chiral HPLC. The conversion yields increase by up to 90% in ON‐resonance conditions. Interestingly, a large increase in the conversion yield does not affect the enantiomeric excess. Further control experiments were carried out by varying the temperature, and we propose that the rate‐limiting step may not be the deciding factor in enantioselectivity. Whereas the formation of the enamine intermediate is modified by cavity coupling experiments. For this class of enantioselective reactions, strong coupling does not change the enantiomeric excess, possibly due to the large energy difference in chiral transition states. Strong coupling can boost the formation of enamine intermediate, thereby favouring the product yield. This gives more hope to test polaritonic chemistry based on enantioselective reactions in which the branching ratios can be controlled.
