high yields by a conventional diazotization-coupling sequence. The chemical structures of the prepared compounds were confirmed by 1H-NMR, 13C-NMR, IR, UV-Vis spectroscopy, mass spectrometry and elemental analysis. In addition, the X-ray single crystal structure of a representative azo dye was presented. For explicit determination of the influence of a substituent on radiation absorption in UV-Vis range
通过传统的重氮化偶联序列,从 2-氨基-5-芳基-1,3,4-噻二唑和苯胺、N,N-二甲基苯胺和苯酚衍生的三个系列偶氮染料以高产率合成。所制备化合物的化学结构经1H-NMR、13C-NMR、IR、UV-Vis光谱、质谱和元素分析确证。此外,还展示了代表性偶氮染料的 X 射线单晶结构。为了明确确定取代基对 UV-Vis 范围内辐射吸收的影响,进行了时间相关的密度泛函理论计算。
