Structure and electronic properties of conjugated organic molecules on transition metal dichalcogenide monolayers (A08)

其目标是全面了解由共轭有机分子和过渡金属二卤化物(TMDC)单分子膜形成的杂化无机/有机体系(HIO)的结构和电子性质。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单分子膜上的van der Waals结合分子的取向和堆积密度的方法。在第二个研究领域，研究强分子电子受体/施主与TMDC单分子膜之间发生的基态电子耦合和电荷转移过程，应该揭示是否存在电荷掺杂或电荷转移络合物的形成。此外，还将研究共价结合到TMDC单分子膜上的光致变色分子开关。

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.
