Abstract Photoacids and bases allow remote control over pH in reaction solutions, which is of fundamental importance to an array applications. Herein, we determine the wavelength‐by‐wavelength resolved photoreactivity triarylsulfonium hexafluorophosphate salts as a representative photoacid generator p ‐(benzoyl)benzyl triethylammonium tetraphenylborate photobase generator, constructing wavelength‐resolved photochemical action plot for each compounds. We monitor change solution on‐line within cavity laser vial demonstrate marked mismatch between absorption spectrum base with plot, unveiling reactivity at very low absorptivities. Our findings are critical use photoacids bases, unambiguously demonstrating that no guide chemical consequences wavelength employed applications bases.
