Substituent and solvent effects on the UV/vis absorption spectra of 5-(3- and 4-substituted arylazo)-4,6-dimethyl-3-cyano-2-pyridones
TL;DR: In this article, the effects of substituents on the absorption spectra of these new azo dyes are interpreted by correlation of absorption frequencies with Hammett equation, and the solute-solvent interactions were clarified on the basis of linear solvation energy relationships concept proposed by Kamlet and Taft.
