Abstract
Superstructures of metal-free phthalocyanine (2H-Pc) molecules on graphene-covered Ir(111) have been explored by scanning tunnelling microscopy. Depending on the sub-monolayer coverage different molecular assemblies form at the surface. They reflect the transition from a graphene template effect on the 2H-Pc arrangement to molecular superstructures that are mainly governed by the intermolecular coupling.
摘要
通过扫描隧道显微镜研究了石墨烯覆盖的Ir(111)上无金属酞菁(2H-Pc)分子的超结构。根据亚单层覆盖情况，表面会形成不同的分子组装体。它们反映了从石墨烯对2H-Pc排列的模板效应到主要由分子间耦合主导的分子超结构的转变。
