Stability of Styryl Hemicyanine Dyes in Water by Fábio Nery de Assis is a document available to read on EtoBox.
The study investigates the stability and self-association of five styryl hemicyanine dyes in water using 1H NMR spectroscopy, revealing that these compounds are stable at acidic and neutral pH but undergo ring opening at basic pH. Substituting certain functional groups enhances stability and affects self-association constants, with the most hydrophobic derivative showing the highest self-association constant and lowest Gibbs energy. The findings have implications for the selection of dyes for applications i
