| 摘 要： | 合成了四个二苯并四硫代富瓦烯(DB-TTF)的衍生物(3a～b, 4a～b), 给出了它们的核磁共振氢谱和碳谱, 质谱,紫外吸收光谱及元素分析等数据. 用=循环伏安法测定了它们的氧化电位, 并将此与DB-TTF的氧化电位作了比较.发现: 两端取代的硫酮基对分子体系的吸电子效应较强,会明显增大分子的第一氧化电位 , 而且会降低分子内的Coulomb作用力, 相比之下, 在四周顶点上取代的烷氧基对分子体系的给电子效应较弱.

| Abstract: | Four dibenzotetrathiafulvalene (DB-TTF) derivatives (3a- b, 4a- b) were synthesized. Their 1H NMR, 13C NMR, Mass, and UV asorption spectra as well as cyclic voltammetry data (CV) were given. CV behaviours of these compounds were compared with that of DB-TTF. It was indicated that thio-ketonic groups substituted at the terminals of DB-TTF gave a larger first oxidation potential and a less coulomb interaction. Meanwhile, four alkoxy groups located at the periphery of the molecule gave only a little change of the properties of the parent molecule. |
