dc.description.abstract | Six donor-pi-acceptor azo dyes, with altered donor- (p-hydroxyphenyl-and naphthalene-2ol) and carboxylic based acceptor groups, were subjected to detailed solvatochromic and tautomeric investigation in different environments by experimental and theoretical approaches. Naphthalene2-ol compounds exhibit azo-hydrazone tautomerism in all solvents, wherein benzoic-and cinnamic acid-based compounds appear in solutions as a complex system of neutral forms and corresponding carboxylates. p-Hydroxyphenyl based compounds adopt the azo form in all investigated solvents. A special focus was placed on the definition of the anionic species and the extent of the deprotonation in different alkaline solutions. Excellent agreement between theoretical and experimental data is attained. | en |
