Abstract
• Electron-deficient 5-hydroxyisoquinolones are superphotoacids. • Estimation of pKa* is most authentic from emission spectra. • Solvent scale transfer of pKa* is not reliable. Four electron-deficient 5-hydroxyisoquinolones are among the strongest currently known superphotoacids with excited state pK a * down to −5.8 and ΔpK a up to 9.0, as estimated experimentally via Förster cycle and supported by quantum chemical calculations. A condensed teracyclic derivative is a weaker photoacid with ΔpK a of around three units. The superphotoacidity in turn initiates pH-switched Stokes shifts: irrespective of the form (protonated or deprotonated) absorbing the photon, only emission of the deprotonated form is observed in protic media.
