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

在该项目中，将通过应用不同的合成策略分别制备基于二茂铁的树枝状化合物和树枝状聚合物，其特征在于二茂铁基单元作为末端接枝部分（化合物2、5、6和17-20）。对于其表征，将使用元素分析、光谱方法（FT-IR; 1H，13 C {1H} NMR）和高分辨率ESI-TOF质谱法。如果合适，将通过单晶结构分析确定所选物质的分子固态结构。用方波伏安法（SWV）、循环伏安法（CV）和线性扫描伏安法（LSV）研究了化合物的电化学行为。为了表明，如果电子通信发生在适当的混合价物种原位紫外可见/近红外光谱将被应用。此外，还将进行现场EPR研究和穆斯堡尔光谱测量。此外，将进行固态电化学研究，以了解树枝状分子/树枝状聚合物对电荷存储应用的有效性。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.
