1 H NMR Chemical Shift as an Index of UV-Vis Absorption/Emission Maxima in Aromatic Dyes

BSBartosz SzymańskiCFCina Foroutan‐Nejad

Key Points

  • This research aims to explore the relationship between ¹H NMR chemical shifts and UV-Vis absorption/emission maxima in aromatic dyes.
  • Experimental analysis of ¹H NMR chemical shifts in structurally related aromatic dyes.
  • Comparative evaluation of these shifts against measured optical maxima.
  • Chemical shifts were found to correlate directly with UV-Vis absorption maxima across multiple dye families.
  • Predictions of emission maxima were also validated through experimental results.

Abstract

We have demonstrated that experimental ¹H NMR chemical shifts can serve as direct indicators of absorption and emission maxima within families of structurally related molecules. Notably, predictions of optical maxima...
