excited-state photoacids
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Most of proton chemistry is driven by a high concentration of protons ([H+]), which is difficult to obtain using excited-state photoacids.
Usefulness & Problems
Why this is useful
Excited-state photoacids are presented as light-responsive acids used for proton chemistry. In this review they mainly serve as a comparison class for mPAHs.; photo control of proton chemistry

mPAHs have been applied across chemical, material, energy, biotechnology, and biomedical fields, including systems driven by acid-base reactions, acid-catalyzed reactions, ionic bonding, coordination bonding, hydrogen bonding, ion exchange, cation-pi interaction, solubility, swellability, permeability, and pH change in biosystems.
Photoacids enable spatial, temporal, and remote control of proton chemistry by transforming from weak to strong acids under light.
Metastable-state photoacids can reversibly generate high proton concentration under visible light with moderate intensity, addressing a limitation of excited-state photoacids for proton chemistry requiring high [H+].
The review compares mPAHs with excited-state photoacids and with common acids such as HCl to explain mPAH advantages.
Merocyanine, indazole, and TCF mPAHs are compared in the review with respect to photo-induced proton concentration, switching rate, and other properties.
