Ferrocene-/Ferrocenyl-functionalized Dendrimers: Synthesis, Characterization and their Electrochemical Behavior

在这个项目中，将通过不同的合成策略分别制备以二茂铁基为末端接枝单元的树枝状化合物和树枝状大分子(化合物2、5、6和17-20)。对于它们的表征元素分析，将使用光谱分析方法(FT-IR；1H，13C{1H}核磁共振)和高分辨率ESI-TOF质谱仪。如果合适，将通过单晶结构分析确定所选物种的分子固态结构。用方波(SWV)、循环(CV)和线性扫描伏安法(LSV)测定了所制备化合物的电化学行为。为了表明，如果在适当的混合价物种中发生了电子通信，将使用原位UV-Vis/NIR光谱。此外，还将进行现场EPR研究以及Möber Bauer光谱测量。此外，还将进行固态电化学研究，以了解树枝状分子/树枝状大分子在电荷存储应用中的有效性。其结果将与例如我们工作组最近制备的聚乙烯基二茂铁进行比较。

Within this project, ferrocene-based dendritic compounds and dendrimers, respectively, featuring ferrocenyl units as end-grafted moieties (compounds 2, 5, 6 and 17–20) will be prepared by applying different synthetic strategies. For their characterization elemental analysis, spectroscopic methods (FT-IR; 1H, 13C{1H} NMR) and high-resolution ESI-TOF mass-spectrometry will be used. If appropriate, the molecular solid state structure of selected species will be determined by single crystal structure analysis. The electrochemical behavior of the prepared compounds will be determined by square-wave (SWV), cyclic (CV) and linear sweep voltammetry (LSV). To show, if electronic communication occurs in the appropriate mixed-valent species in situ UV-Vis/NIR spectroscopy will be applied. In addition, in situ EPR studies as well as Mößbauer spectroscopic measurements will be carried out. Furthermore, solid state electrochemical studies will be performed in order to understand the validity of the dendritic molecules/ dendrimers toward charge storage applications. The results thereof will be compared with, for example, polyvinyl-ferrocenes, which have been recently prepared within our working group.
