mophenyl)-1-(4-substituted-phenyl)formazan (4a-4h) were synthesized by coupling of substitutedphenylhydrazones with diazonium salts of 4-bromoaniline. The substitutedphenylhydrazones, which are intermediate products, were obtained from the condensation of substituted phenylhydrazines with 4-(benzyloxy)benzaldehyde. All target compounds were characterized by using FTIR, $^1}$H NMR, $^13}$C NMR,
通过将取代的苯hydr与4-溴苯胺的重氮盐偶联,合成了八种新型的3-(4-(苄氧基)苯基)-5-(4-溴苯基)-1-(4-取代的苯基)甲酰胺(4a-4h)。 。由取代的苯肼与4-(苄氧基)苯甲醛缩合获得中间体产物的取代的苯hydr。所有目标化合物均通过FTIR,$ ^ 1} $ H NMR,$ ^ 13} $ C NMR,LC $-$ MS光谱和元素分析进行表征。彻底研究了这些化合物在不同极性溶剂中的吸收光谱。进行了时变密度泛函理论(TD-DFT)研究,以阐明其电子结构,科恩-沙姆(Kohn-Sham)轨道和电子跃迁。
