New 1,3,4-thiadiazole derivatives containing a diazenyl group, as well as both a diazenyl and an imino group, were synthesized and their optical and thermal properties were investigated. Initially, new azo compounds containing an azo group directly in the thiadiazole block were obtained by the coupling of diazonium bisulfates based on the previously known 5-derivatives of 2-amino-1,3,4-thiadiazoles
合成了新的 1,3,4-噻二唑衍生物,包含一个二氮烯基,以及一个二氮烯基和一个亚氨基,并研究了它们的光学和热性能。最初,通过将基于先前已知的 2-氨基-1,3,4-噻二唑的 5-衍生物的重氮硫酸氢盐与N , N-二烷基苯胺偶联,获得了在噻二唑嵌段中直接含有偶氮基团的新偶氮化合物( N( n- Bu) 2、NEt 2和NEt(EtOH))。通过对甲苯胺、对苯二胺和对苯二胺的相互作用获得席夫碱-氨基苯酚与在 1,3,4-噻二唑环中含有醛基的偶氮化合物。通过光谱(IR、UV、1 H NMR、13 C NMR 和质谱)和 X 射线分析对新染料进行了表征。
