Excited State Dynamics of CO₂ Reduction Catalyst under Vibrational Strong Coupling.

ABSTRACT: Molecular polaritons, formed by coupling molecular electronic or vibrational transitions to photonic modes in microcavities, have gained interest for their potential to influence chemical dynamics. Here, we investigate the effects of vibrational strong coupling (VSC) on solvation-induced time-dependent Stokes shifts using transient infrared (IR) transmission spectroscopy. The electronic excited-state dynamics of the Re(bpy-COOH)(CO)₃Cl complex (ReC0A) is monitored via angle-resolved time-dependent transmission spectra of vibrational polaritons following 400 nm excitation inside a Fabry-Perot cavity. Our results reveal distinct infrared polaritonic signatures of the CO dynamical Stokes shift, which we interpret using simulations based on a time-dependent excited-state absorption
