corresponding N,N′-diamides, which were converted into N,N′-dithioamides by reacting with Lawesson’s reagent. A method was developed for the preparation of previously unknown fused systems, dithiazolobenzo[1,2-c][1,2,5]thiadiazoles and dithiazolobenzo[1,2-d][1,2,3]triazoles, by oxidative photochemical cyclization of N,N′-dithioamides. The photophysical and (spectro)electrochemical properties of the obtained
苯并[ c ][1,2,5]噻二唑-4,7-二胺和2-己基-2H-苯并[ d ][1,2,3]三唑-4,7-二胺与芳香酰卤的酰化提供了相应的N,N'-二酰胺,通过与 Lawesson 试剂反应将其转化为N,N'-二硫代酰胺。开发了一种通过氧化光化学制备以前未知的稠合系统、二噻唑并苯并[1,2- c ][1,2,5]噻二唑和二噻唑并苯并[1,2- d ][1,2,3]三唑的方法N , N的环化'-二硫代酰胺。研究了所得化合物及其电化学沉积在 ITO 上的聚合物薄膜的光物理和(光谱)电化学性质。测定了合成低聚物的光学对比度和响应时间。获得的结果使我们能够将这些物质视为电致变色设备的有前途的候选者。
