Polariton chemistry is a new class of chemistry that occurs in strongly confined environments, such as optical cavities, where light-matter interactions are modified by the strong coupling limit. In this issue of Chem, Du et al. show a theoretical example where a catalyst is capable of inducing a reaction without touching the reactant when both are confined in a quantum-based optical device. Thanks to the strong coupling of two adjacent optical cavities, the study demonstrates that it would be possible to drive the cis → trans conformational isomerization of nitrous acid, contained in one cavity, by increasing the photoexcitation of glyoxylic acid in another cavity
