Excited State Dynamics of CO <sub>2</sub> Reduction Catalyst under Vibrational Strong Coupling
Journal of the American Chemical Society · 2025-10-10 · 2 citations
articleOpen accessSenior authorCorrespondingMolecular 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-depende…
Photodriven water oxidation initiated by a surface bound chromophore-donor-catalyst assembly
UNC Libraries · 2025-10-30
articleOpen accessSenior authorIn photosynthesis, solar energy is used to produce solar fuels in the form of new chemical bonds. A critical step to mimic photosystem II (PS II), a key protein in nature's photosynthesis, for artificial photosynthesis is designing devices for efficient light-driven water oxidation. Here, we describe a single molecular assembly electrode that duplicates the key components of PSII. It consists of a polypyridyl light absorber, chemically linked to an intermediate electron donor, with a molecular-b…
