Study of Synthesis and Physical Properties of New Electron Donor Compounds Incorporating Ferrocene Moiety as New Conductors

寻找新的电活性材料是目前化学家们非常活跃的研究课题。近年来，合成新的π扩展给体已成为许多化学家感兴趣的领域。用含二茂铁基团的共轭间隔剂分离了若干π-扩展共轭四硫代富勒烯（TTF）类似物作为新的π-给体，并通过实验技术和光谱分析对其结构和物理性质进行了表征。以二茂铁和二茂铁醌为对照，研究了扩展二茂铁给体的紫外可见光谱和循环伏安。以单波形式观察到三电子氧化还原行为。吸收光谱显示出轻微的红移和强度的轻微增加。另一方面，报道了一种合成新型四硫代戊二甲酯（TTF-DME）的简便方法。通过引入酯配位功能作为双官能团的新给体，制备了四硫代戊二甲基醚ttf -二甲醚。用循环伏安法研究了TTF-DME的氧化还原行为，并与众所周知的DB-TTF进行了比较。观察到双电子氧化还原行为为两波。此外，二茂铁基酮化合物的合成并进行作为Wittig-Horner反应的开始是我们主题的目的。二茂铁基酮通过上述方法合成，并与1,3 -苯二噻唑-2-膦酸酯在n-BuLi存在下，在- 78℃的干燥四氢呋喃中反应生成相应的二茂铁-二硫代烯（Fc-DTF）和二茂铁-四硫代烯（Fc-TTF）。利用紫外可见光谱和循环伏安分光光度计（CV）研究了新给体化合物的电化学性质。并与二茂铁和二苯并四噻吩进行了循环伏安（CV）和吸收光谱的比较。两个电子和三个电子的氧化还原行为作为两个波被观察到。

The search for new electro active materials is nowadays very active field of research topic for chemists. Recently, the synthesis of new π-extended donors has become a great area of interest for many chemists. A number of π-extended conjugated tetrathiafulvalen (TTF) analogues separated by a conjugated spacer incorporating ferrocene moiety were successively synthesized as new π-donors and their structure and physical properties were characterized both by experimental techniques and spectral analysis. UV-Vis spectra and cyclic voltammetry of the π-extended ferrocenyl donor were studied in comparison with ferrocene, and ferrocenylquinone. A three-electron redox behavior was observed as a single wave. The absorption spectrum showed a slight red-shift and slight increase in the intensity.On the other hand, a simple route for synthesis of new tetrathiafulvalene dimethyl ester (TTF-DME) is reported. The tetrathifulvalene dimethylester TTF-DME has been prepared by introducing an ester coordination function as a bifunctional new donor. The redox behavior of the TTF-DME was investigated in comparison to the well-known DB-TTF by cyclic voltammetry. A two-electron redox behavior was observed as a two waves.Moreover, the synthesis of ferrocenylketone compounds and conducted to be a starting for the Wittig-Horner reaction is the aim of our topic. The ferrocenylketones have been synthesized via described methods, and allowed to react with l,3-benzodithiole-2-phosphonate ester in the presence of n-BuLi at - 78℃ in dry THF to afford the corresponding ferrocene-dithiafulvalenes (Fc-DTF's) and ferrocene-tetrathiafulvalene (Fc-TTF). Electrochemical properties of the new donor compounds were studied using UV-Vis spectra and cyclic voltamogram spectrophotometer (CV). Cyclic voltammetry (CV) and absorption spectra of the new compounds were studied in comparison with ferrocene and dibenzo-tetrathiafulvalene. A two-electron and three-electron redox behavior was observed as a two waves.
