摘要

class="kwd-title">Keywords: 3-Chloroformazans, Azo compounds, Pyrazoles, Imidazoles, Heterocycles, Solvatochromism class="head no_bottom_margin" id="ab010title">AbstractA simple synthetic strategy for synthesis of new series of hetarylazo-heterocycles is described. The effects of solvent on their electronic absorption spectra were analyzed using Kamlet–Taft equation. The results of fitting coefficients indicated that the solvatochromism of the studied compounds is mainly due to the solvent polarity rather than the solvent basicity and acidity.
