AB  - A series of eleven new 5-arylazo-6-hydroxy-4-(4-methoxyphenyl)-3-cyano-2-pyridone dyes was synthesized and their absorption spectra were recorded in twenty solvents in the range 300-600 nm. Different solvent parameters, such as microscopic solvent polarity, E-T(N), relative permittivity, epsilon(r), refractive index, n, the Kamlet-Taft and the Catalan parameters were used for the evaluation of the solute-solvent interactions and the solvatochromic shifts of the UV-vis absorption maxima of the hydrazone tautomeric form of the investigated arylazo pyridone dyes. The Catalan solvent scales are found to be the most suitable for describing the solvatochromic behavior of the dyes.

AB  - A series of ten new 5-arylazo-6-hydroxy-4-(4-nitrophenyl)-3-cyano-2-pyridone dyes was synthesized using a classical reaction for the synthesis of azo compounds. The structure of the dyes was confirmed by melting point, elemental analysis, UV-vis, FT-IR, H-1 NMR and C-13 NMR spectroscopic techniques. The absorption spectra were recorded in twenty solvents of different properties in the range of 300-700 nm. In order to describe the spectral changes and the solute-solvent interactions, multiparameter Kamlet-Taft and Catalan solvent scales were used. The Catalan solvent scales are found to be the most suitable for describing the solvatochromic behavior of the synthesized dyes. The effect of the substituents on the azo-hydrazone tautomeric equilibrium was analyzed using the simple Hammett equation. For the synthesized dyes, the Hammett polar susceptibility constant (rho) was correlated through multiple regression using appropriate solvent parameters.

AB  - A series of 4,6-disubstituted-3-cyano-2-pyridones was synthesized and their UV-Vis absorption spectra were recorded in the region 200-600 nm in the set of selected solvents. The effects of solvent dipolarity/polarizability and solvent-solute hydrogen-bonding interactions on the spectral shifts were analyzed by means of the linear solvation energy relationship concept of Kamlet and Taft. The influence of solvents as well as substituents on the 2-pyridone/2-hydroxypyridine tautomeric equilibration was evaluated. The absorption band maximum of the 2-hydroxypyridine form is found to appear at a shorter wavelength than that of the 2-pyridone form in all investigated solvents. The replacement of the methyl and phenyl groups at position 6 of the pyridone ring, by a hydroxy group, significantly changes the solvatochromic behavior of the investigated pyridones.

AB  - Background: A series of some novel arylazo pyridone dyes was synthesized from the corresponding diazonium salt and 6-hydroxy-4-phenyl-3-cyano-2-pyridone using a classical reaction for the synthesis of the azo compounds. Results: The structure of the dyes was confirmed by UV-vis, FT-IR, H-1 NMR and C-13 NMR spectroscopic techniques and elemental analysis. The solvatochromic behavior of the dyes was evaluated with respect to their visible absorption properties in various solvents. Conclusions: The azo-hydrazone tautomeric equilibration was found to depend on the substituents as well as on the solvent. The geometry data of the investigated dyes were obtained using DFT quantum-chemical calculations. The obtained calculational results are in very good agreement with the experimental data.
