Some novel benzoquinoline based heterocyclic monoazo dyes have been derived by the diazotization of 1H-benzo[g]pyrazolo[3,4-b]quinoline-3-ylamine with various phenyl pyrazolone as coupling components. All the heterocyclic monoazo dyes have been characterized by elemental analyses and various spectral data (FT-IR, UV–Vis, 1H NMR and 13C NMR), and their 3D model structures were predicted through B3LYP/6-31G(d
通过将1H-苯并[g]吡唑并[3,4-b]喹啉-3-基胺与各种苯基吡唑啉酮作为偶合组分进行重氮化,已经得到了一些新颖的基于苯并喹啉的杂环单偶氮染料。所有杂环单偶氮染料均已通过元素分析和各种光谱数据(FT-IR,UV-Vis,1 H NMR和13 C NMR)进行了表征,并通过B3LYP / 6-31G(d,p ) 方法。聚酯纤维的染色性能可以推断,所有染料在纤维上均具有中等至极好的坚牢度。另外,还讨论了合成染料的比色研究。
