Abstract

The effect of specific hydrogen-bonding interactions on the electronic spectra and the infrared (IR) absorption spectra of several naphthol-type photoacids was investigated. A correlation between the pK_a ^* of the photoacid and its optical solvatochromism was observed for R*O-H⋯B-type hydrogen bonds using the Kamlet-Taft (K-T) analysis. In addition, a correlation between the spectral shift in the IR stretching frequency of the R*O-H⋯B bond and the optical Stokes shift in the fluorescence spectra of the photoacids was found.
