Synthesis and Properties of Molecular Inorganic/Organic/Inorganic Multilayer Clusters (A09)

为了在分子尺度上理解界面的几何结构和电子结构，我们研究了具有无机过渡金属硫属化物MxEy核的结晶多层纳米团簇（M =过渡金属，E = S、Se、Te），四元二硫属化物TE2单元的第一包围壳（T = Ge，Sn）和具有官能有机基团的共价结合的外部配体壳，用于与（半）金属原子或表面进一步相互作用。通过改变M，T和E，我们探索了各种组件对它们之间的界面的性质的影响，也与相同的金属（二）硫属化物组合物的堆叠的2D系统相比。

For understanding of geometric and electronic structures of interfaces at the molecular scale, we address crystalline multilayer nano-clusters with an inorganic transition metal chalcogenide MxEy core (M = transition metal, E = S, Se, Te), a first surrounding shell of tetrel dichalcogenide TE2 units (T = Ge, Sn) and a covalently bound, outer ligand shell with functional organic groups for further interaction with (semi-)metal atoms or surfaces. By varying M, T and E, we explore the effect of the various components on the nature of the interfaces between them, also in comparison with stacked 2D systems of the same metal (di-)chalcogenide composition.
