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.

Four dibenzotetrathiafulvalene (DB-TTF) derivatives (3a～b, 4a～b) were synthesized . their ^1H NMR, ^1^3C 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 .
