Metal-organic framework electrosynthesis
Metal-organic frameworks (MOFs) constitute an important class of complex functional materials relevant, amongst others, for sensing, catalysis, optoelectronics and energy storage and conversion applications. However, the growth process, particularly the nucleation phase and the early growth stages that govern the final material properties, are not fully understood yet. Such knowledge is crucial for the design of tailored bottom-up MOF fabrication protocols.
We characterize the initial stages of potential-controlled MOF growth as a function of applied substrate potential, electrolyte composition, substrate morphology and functional ligands in situ with unprecedented molecular topographic and chemical resolution. Based on the detailed mechanistic insight into the molecular interactions underlying (early stage) MOF growth thus gained, we can rationally design improved preparation protocols for MOFs with desired properties.
