3,4-二氯异噻唑及3,5-二氯甲苯衍生物的紫外-可见光谱对比分析

Comparative Analysis of UV-Vis Spectra of 3,4-Dichloroisothiazole and 3,5-Dichlorotoluene Derivatives

摘要: 异噻唑环是一种不同于苯环的芳香类杂环，本文通过合成3,4-二氯异噻唑和3,5-二氯甲苯两类衍生物，并对它们的紫外–可见光谱进行对比分析，比较其吸收波长的特征，探究其紫外吸收波长因结构功能基团的改变而产生的变化，进一步地分析探索这类具有农药功能异环芳香类衍生物的结构与性质。

Abstract: Isothiazole ring is a kind of aromatic heterocyclic which is different from phenyl ring. In this paper, 3,4-dichloroisthiazole and 3,5-dichlorotoluene derivatives were synthesized. Their electronic spectra had been determined that absorption wavelength was compared and analyzed. Furthermore, in order to explore the structures and properties of these heterocyclic aromatic derivatives with pesticide function, the research in the paper investigated the influence of different functional groups on maximum absorption.
