Abstract

A 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.

摘要

描述了一种简单的杂芳基偶氮杂环新系列的合成策略。使用 Kamlet-Taft 方程分析了溶剂对它们的电子吸收光谱的影响。拟合系数的结果表明，研究化合物的溶剂致变色主要是由于溶剂的极性，而不是溶剂的碱性和酸性。
