Many chemical methods have been developed to favor a particular product in transformations of compounds that two or more reactive sites. We explored different approach site selectivity using vibrational strong coupling (VSC) between reactant and the vacuum field microfluidic optical cavity. Specifically, we studied reactivity compound bearing possible silyl bond cleavage sites-Si-C Si-O, respectively-as function VSC three distinct modes dark. The results show can indeed tilt landscape one...

Vibrational strong coupling (VSC) has recently emerged as a completely new tool for influencing chemical reactivity. It harnesses electromagnetic vacuum fluctuations through the creation of hybrid states light and matter, called polaritonic states, in an optical cavity resonant to molecular absorption band. Here, we investigate effect vibrational water on enzymatic activity pepsin, where molecule is directly involved enzyme's mechanism. We observe approximately 4.5-fold decrease apparent...

Abstract Vibrational strong coupling (VSC) is currently emerging as a tool to control chemical dynamics. Here we study the impact of strength, given by Rabi splitting energy ( ħ Ω R ), on thermodynamic parameters associated with transition state desilylation reaction model molecule 1-phenyl-2-trimethylsilylacetylene. Under VSC, enthalpy and entropy activation determined from temperature-dependent kinetic studies varied nonlinearly strength. The noncavity did not show noticeable variation,...

Abstract Vibrational strong coupling (VSC) has recently been shown to change the rate and chemoselectivity of ground‐state chemical reactions via formation light–matter hybrid polaritonic states. However, observation that vibrational‐mode symmetry a large influence on charge‐transfer under VSC suggests considerations could be used control other types selectivity through VSC. Here, we show influences stereoselectivity thermal electrocyclic ring opening cyclobutene derivative, reaction which...

In quantum electrodynamics, matter can be hybridized to confined optical fields by a process known as light–matter strong coupling. This gives rise new hybrid states and energy levels in the coupled material, leading modified physical chemical properties. Here, we report for first time coupling of vibrational modes proteins with vacuum field Fabry–Perot mid-infrared cavity. For two model systems, poly(l-glutamic acid) bovine serum albumin, is confirmed anticrossing dispersion curve, square...

Enhancing the electrical conductance through amorphous nondoped polymers is challenging. Here, we show that vibrational strong coupling (VSC) of intrinsically nonconducting and such as polystyrene, deuterated poly(benzyl methacrylate) to vacuum electromagnetic field cavity enhances conductivity by at least 6 orders magnitude compared uncoupled polymers. Remarkably, observed extraordinary mode selective occurs only under VSC aromatic C–H(D) out-of-plane bending modes The thermally activated...
