Novel merocyanine dyes cyanine dyes derived from benzo[2,3-b; 2′, 3′ - b′ ]bis pyrazolo[4,5-b]-l,4-(oxa-, thia-, and pyra)-zine-6,12-dione ring system were prepared. The prepared cyanines involve acyclic merocyanine and cyclic merocyanine types. Colour spectrophotometric measurements for all the synthesized merocyanine dyes were investigated in 95% ethanol solution. Colour spectrophotometric measurements
新型花菁染料衍生自苯并[2,3-b; 制备了2',3'-b']双吡唑并[4,5-b] -1,4-(oxa-,thia-和pyra)-zine-6,12-dione环系统。制备的花青涉及非环花青和环花青类型。在95%乙醇溶液中研究了所有合成的花菁染料的分光光度法测量值。在具有不同极性的纯溶剂中和/或在通用缓冲水溶液中检查了一些选定的合成花青的分光光度测量。通过元素分析,IR和1 H NMR光谱数据进行了常规化学-物理表征。
