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.

在我们以前的贡献中，我们展示了组装的heterodecoxobenzene金属配合物在一个控制的方式，通过使用正交配体。金属离子彼此之间的距离基本上受配体和离子大小的影响。金属离子的特定组合、离子间的距离以及给体配体的电子性质都可以影响配合物的物理化学性质。在本计画中，我们将合成具有正交配位体的杂环香豆素金属配合物，其配位体的侧链将被香豆素衍生物作为染料而官能化。在前期工作的基础上，提出了不同风险等级的研究方案。将采取逐步的方法，首先针对简单的配体及其配合物的合成。通过改变金属和它们彼此之间的距离，金属离子之间的相互作用以及因此的“配体-金属-金属电荷转移”（LMMCT）以及所得的电子物理性质将被具体控制。
