Аннотация: Fluorescent properties of 5-hydroxyisoquinolone-3,4,6,7,8- pentacarboxylates and their 4,6,7,8-tetracarboxylate analogs lacking a 3-positioned electron-withdrawing ester group differ substantially. The presence of an electron-withdrawing group at position 3 in the 5-hydroxyisoquinolone system was found crucial for their vibrational relaxation in the anionic forms, which highlights the importance of substitution pattern providing valuable insights for future research in this area.

Ключевые слова: fluorescence, photoacidity, vibrational relaxation, 5-hydroxyisoquinolones, isoquinolones, Stokes shift, TD-DFT.
