Investigations on the synthesis and coordination chemistry of silicon analogues of crown ethers and cryptands with Si2 units

这个项目的主要目标是合成和研究在供体原子之间表现出Si2Me4桥的新型冠状物和密码物。作为一种可能的合成途径，计划模板合成以及配体的逐步构建。对这些配体配位性质的研究有助于更好地理解Si-O-Si单元中氧原子的配位性质，从而也为更好地理解硅和氧原子之间的化学键提供了信息。在第一个资助期的过程中，我们已经证明这些配体也可以用于合成不寻常的溶剂化物，并且还能够通过寡聚化适应阳离子的大小。除了对配位的基础研究外，这些配体还计划在合成非常规溶剂化物和锌化学领域中的应用。

The main goal of this project is the synthesis and investigation of novel crownethers and cryptands that exhibit Si2Me4 bridges between the donor atoms. As a possible synthesis pathways, template syntheses are planned as well as stepwise construction of the ligands. Investigations of the coordination properties of these ligands lead to a better understanding of the coordination properties of oxygen atoms in Si-O-Si units and thus also provide information to a better understanding of chemical bonds between silicon and oxygen atoms.In the course of the first funding period we have shown that these ligands can also be used for the synthesis of unusual solvates and are also able to adapt to the size of the cation by oligomerization. In addition to the fundamental investigation of coordination, applications of these ligands in the fields of synthesis of unusual solvates and Zintl chemistry are planned.
