The goal is achieving a comprehensive understanding of the structure and electronic properties of hybrid inorganic/organic systems (HIOS) formed by conjugated organic molecules and transition metal dichalcogenide (TMDC) monolayers. The first research area aims at determining means to tune the orientation and packing density of van der Waals bound molecules adsorbed on the TMDC monolayer, by varying deposition processes and molecular structure. In the second research area, investigations of ground state electronic coupling and charge transfer processes occurring between strong molecular electron acceptors/donors and TMDC monolayers should unravel whether charge-doping or charge transfer complex formation occurs. Also, photochromic molecular switches covalently bound to the TMDC monolayer will be investigated.

我们的目标是实现一个全面的理解的结构和电子性质的混合无机/有机系统（HIOS）形成的共轭有机分子和过渡金属二硫属化物（TMDC）单层。第一个研究领域旨在确定通过改变沉积过程和分子结构来调节吸附在TMDC单层上的货车德瓦尔斯结合分子的取向和堆积密度的方法。在第二个研究领域中，强分子电子受体/供体和TMDC单层之间发生的基态电子耦合和电荷转移过程的调查应该解开是否发生电荷掺杂或电荷转移复合物的形成。此外，光致变色分子开关共价键合到TMDC单层将进行研究。
