Vinylruthenium-modified carbazoles, tetrathiafulvalenes and triarylmethyl-cations as highly efficient poyelectrochromics

本项目旨在合成和表征结晶紫型的咔唑、四硫富瓦烯和三芳基甲基碳正离子的单-四核乙烯基钌配合物，作为用于低能可见光和近红外(NIR)的高效多电致变色材料。深入的IR-UV/VIS/NIR和EPR研究以及伴随的量子化学计算将使我们详细了解这些化合物在所有可用的氧化态下的电子结构。我们在这里寻求对它们的性质和行为的电子起源的理解。在这些基础研究的同时，我们将对我们的络合物进行修饰，使其能够共价连接到透明的半导体二氧化钛或氧化铟锡(ITO)电极上。与康斯坦茨大学物理系的Lukas Schmidt-Mende教授合作，我们将超越分子络合物的探索，将其应用于多电色器件，如智能窗或Grätzel型染料敏化太阳能电池的串联电池，以及从电致变色窗到光触发自调光设备。

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.
