Supramolecular Engineering Of Metal-Organic Networks At Surfaces

摘要

We report the construction of complex metal-organic assemblies at surfaces using concepts from coordination chemistry. Well-ordered supramolecular assemblies and metal-organic coordination networks with specific topologies and a high structural stability have been fabricated under ultra-high vacuum conditions by sequential deposition of polyfunctional organic molecules and Fe atoms onto an atomically clean Cu(100) substrate. The structures were investigated at the molecular level by in-situ scanning tunneling microscopy. The precise control of the concentration ratio of the components and the annealing treatment allow for the assembly of distinct architectures.
