Multinuclear coinage metal complexes with orthogonal ligands

在我们之前的文章中，我们展示了利用正交配体以可控的方式组装杂双金属铸币金属配合物。金属离子之间的距离本质上受配体和离子大小的影响。配合物的光物理性质受金属离子的特定组合、离子的距离和给体配体的电子特性的影响。本课题拟合成以香豆素衍生物为侧链染料的正交配体的杂双金属造币金属配合物。研究计划是在我们前期工作的基础上制定的，包括不同的风险水平。将采取一步一步的方法，首先针对简单配体及其配合物的合成。通过改变金属及其彼此之间的距离，金属离子之间的相互作用以及由此产生的“配体-金属-金属电荷转移”（LMMCT）以及由此产生的光物理性质将被特别控制。

In our previous contribution, we showcased the assembly of heterobimetallic coinage metal complexes in a controlled manner by using orthogonal ligands. The distance of the metal ions to each other is essentially influenced by the ligand and the size of the ions. The photophysical properties of the complexes can be influenced by the specific combination of the metal ions, the distance of the ions and the electronic character of the donor ligand. In the proposed project, heterobimetallic coinage metal complexes with orthogonal ligands functionalized by a coumarin derivative as dye in the side chain will be synthesized. The research plan, which is based on our preliminary work, consist of different risk levels. A stepwise approach will be taken, first aiming at the synthesis of simple ligands and their complexes. By varying the metals and their distances from each other, the interaction between the metal ions and thus the "ligand-to-metal-metal charge-transfer" (LMMCT) as well as the resulting photophysical properties will be specifically controlled.
