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.

该项目的主要目标是合成和研究新型冠醚和穴状配体，它们在供体原子之间表现出Si 2 Me 4桥。作为可能的合成途径，计划进行模板合成以及逐步构建配体。通过对这些配体配位性质的研究，可以更好地理解Si-O-Si-在第一个资助期内，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，并且也能够适应硅和氧原子之间的化学键的大小。阳离子通过低聚反应。除了配位的基础研究，这些配体在合成不寻常的溶剂化物和Zintl化学领域的应用也在计划之中。
