This project aims at the synthesis and characterization of mono- to tetranuclear vinyl ruthenium complexes of carbazoles, tetrathiafulvalenes and triarylmethyl-carbocations of the Crystal violet type as highly efficient polyelectrochromics for the low energy régime of the visible and the near infrared (NIR). In-depth IR- UV/Vis/NIR and EPR-studies and accompanying quantum chemical calculations will provide us with detailed insight into the electronic structures of these compounds in all their available oxidation states. We seek here for an understanding of the electronic origins of their properties and their behaviour. Parallel to these basic studies we will modify our complexes in a manner that allows for their covalent attachment onto transparent semiconducting titania or indium tin oxide (ITO) electrodes. In cooperation with Professor Lukas Schmidt-Mende form the Physics Department at the University of Konstanz, we will go beyond the exploration of the molecular complexes and implement them into polyelectrochromic devices like smart windows or tandem cells of dye-sensitized solar cells of the Grätzel-type and electrochromic windows to light-triggered self-dimming devices.

本项目旨在合成和表征结晶紫型咔唑、四硫富瓦烯和三芳基甲基碳阳离子的单核至四核乙烯基钌配合物，作为可见光和近红外（NIR）低能区的高效聚电致变色剂。深入的IR-UV/维斯/NIR和EPR研究以及伴随的量子化学计算将为我们提供对这些化合物在所有可用氧化态下的电子结构的详细了解。我们在这里寻求了解他们的性质和他们的行为的电子起源。平行于这些基础研究，我们将修改我们的配合物的方式，使其共价连接到透明的半导体二氧化钛或氧化铟锡（ITO）电极。与康斯坦茨大学物理系的Lukas Schmidt-Mende教授合作，我们将超越分子复合物的探索，并将其应用于多电致变色设备，如智能窗户或Grätzel型染料敏化太阳能电池的串联电池和电致变色窗户，以光触发自调光设备。
