Metastable photoacids (mPAH), such as protonated merocyanine, are organic molecules that release protons under illumination, providing spatiotemporal control of pH. While merocyanine-type photoacids enable fully reversible pH cycling in water, their solubility is limited and chemical stability 350 hours of light-induced pH cycling with 10 times more protons released per cycle in water-DMSO mixtures compared to pure water. This solva-tion engineering approach can be applied to other metastable photoacids, serving as a steppingstone towards practical use in applications where long-term stability is critical. |
