Rapid Electrochemical Assessment of Excited-State Quenching Dynamics.

ABSTRACT: Recent advancements in electro-photoredox catalysis (e-PRC) and consecutive photoinduced electron transfer (conPET) have pushed the energy limits of conventional photocatalysis. Both methods produce open-shell intermediate catalysts that, upon light absorption, become highly reducing or oxidizing, enabling challenging reactions. Despite their widespread use, the mechanisms of e-PRC and conPET reactions remain debated, in part due to a lack of quantitative data in most studiesparticularly single-electron transfer rate constants (k _SET) between excited-state catalysts and substrates. We present a straightforward electrochemical method for determining k _SET using cyclic voltammetry (CV) under light irradiation, paired with electrochemical simulation. Using
