Resumen:
Molecular self-assembly is at the core of many relevant processes in nature and material science. Scanning tunneling microscopy (STM) is a powerful tool to study dynamically the self-assembly of nanostructures at conductive surfaces. We focus in the design of hybrid networks by careful selection of the organic molecular ligand, the central metal ions, their relative concentration, and an appropriate substrate [1]. This allows us to control the atomic position of metal centers and the morphology of the networks.Terephthalic acid (TPA) molecules are excellent building blocks in the design of molecularnanostructures, due to their ability to form robust networks with both transition [2,3] and alkali (Group 1) atoms [4,5] on solid surfaces.Inspired by the active site of a key enzyme in the natural process of photosynthesis (RuBisCO) we designed the first network using an alkaline earth metal (Group 2): magnesium (Mg). Here we present a method for producing stable networks of Mg and TPA molecules by direct deposition onto a clean metal Cu(100) substrate. Once the networks are formed, we track their reactivity and dynamic response to carbon dioxide
