通过XPS和FT-IR测试分析,探索了碘掺杂含硫聚席夫碱过程的反应机理,确定了含硫聚席夫碱-碘CT络合物的电子供受关系及其结构。结果表明,聚合物经过碘掺杂后,形成CT络合物而使导电性增加,聚合物中的氮原子供出电子形成=(?)—及=(?)=结构,而掺杂剂碘接受电子形成Ⅰ~-、Ⅰ_3~-和Ⅰ_5~-。CT络合物经二甲胺水溶液脱掺杂后,聚合物可基本回复到其起始态。 Through XPS and FT-IR test and analysis, the reaction mechanism of iodine-doped sulfur-containing poly-Schiff base was explored, and the electron-donor relationship and structure of sulfur-containing Schiff base-iodine CT complex were determined. The results show that after the polymer is doped with iodine, the CT complex is formed and the conductivity is increased. The electron donation of the nitrogen atom in the polymer is (=) = (?) - = = and the dopant iodine Accept the formation of Ⅰ ~ -, Ⅰ_3 ~ - and Ⅰ_5 ~ -. After the CT complex is dedoped by the aqueous solution of dimethylamine, the polymer can basically return to its initial state.
