چکیده

The maximum absorption wavelengths of 31 azo dyes have been calculated by two comprehensive methods using the semiempirical quantum chemical method, PM3, and the weight decay based artificial neural network (WD-ANN) or the early stopping based artificial neural network (ES-ANN). The average absolute errors of WD-ANN and that of ES-ANN are 10.07 nm and 12.40 nm, respectively. These results are much better than the results using ZINDO/S with the default value (0.585) only.

Dyeing Properties of Some New Disperse Dyes Containing Piperazine Moiety

Four novel azo disperse dyes based on 1-4-bromobenzyl-4-phenylpiperazine were synthesized in two steps, using alkylation and azo coupling reactions. Chemical structure of the dyes was characterized and confirmed by the Ultraviolet Visible UV-Visible, Fourrier Transform Infrared FT-IR, Proton Nuclear Magnetic Resonance 1H NMR and Carbon Nuclear Magnetic Resonance 13C NMR analyses. The solvatochr...

Transannular Interaction in N-Aryl-5-Azocanones, A Semiempirical Quantum Mechanics and UV Spectroscopy Studies

The ability of the present semiempirical quantum mechanics methods are surveyed for reproducing the transannular interaction in the bifunctional N-phenyl-5-azocanones. The AM1 method is the best with the order of reliability being Am1, PM3, MNDO and MINDO/3. AM1 calculations were then carried out for quantification of transannular interaction. The n(o) ionization potential has be...
