Recent Progress in Vibropolaritonic Chemistry

Vibrational polaritonic chemistry is emerging as an exciting new sub‐field of chemistry, one in which strong interactions with optical cavity vacuum fields are another degree of freedom alongside temperature, solvent, catalyst, and so on to modify thermochemical reactivity. The field stands at a fascinating juncture with experimental works on a variety of organic reactions continuing to blossom, just as many theoretical works appear which diverge significantly in their predictions compared to experiments. The outlook for the field is no doubt an exciting one as it seeks to unify the observed novel optical cavity‐induced chemical phenomena with satisfying accompanying physical theory. In this minireview we highlight experimental works on vibrational polaritonic chemistry that have appeared most recently, focusing on the chemistry of the rate‐limiting steps to provide mechanistic insight. We hope this review will encourage synthetic chemists to enter the field and we discuss the opportunities and challenges that lie ahead as polaritonic chemistry grows into the future. Vibrational strong coupling: When the vibrational modes of molecules couple strongly to the vacuum electric fields of a Fabry‐Pérot (FP) cavity, new vibro‐polaritonic states are formed. Vibrational strong coupling (VSC) has emerged as a new tool for modulating chemical reactions. This review article provides a comprehensive summary of the recent progress in VSC‐modulated chemical reactions.
