Our research explores host-guest chemistry and molecular recognition at surfaces, focusing on how tailored molecular architectures can control interactions at the nanoscale. By designing and assembling supramolecular networks on metallic and insulating surfaces, we investigate the mechanisms driving molecular confinement, selective adsorption, and dynamic host-guest interactions.
In our studies, we have examined porous molecular frameworks capable of trapping guest molecules, enabling selective recognition through non-covalent interactions such as hydrogen bonding, metal coordination, and van der Waals forces. These systems, often based on organic linkers and functionalized macrocycles, serve as platforms for studying adsorption phenomena and templated self-assembly. For instance, we have explored molecular traps for fullerenes and coordination-driven frameworks that exhibit adaptive host-guest behavior.
To characterize these interactions, we utilize spectroscopic and microscopic techniques to probe molecular organization and stability at surfaces. Our combined experimental and theoretical approach provides insights into the key factors governing chemical recognition, with potential applications in molecular sensing, catalysis, and nanostructured material design. By advancing the understanding of host-guest chemistry at interfaces, we contribute to the development of functional molecular architectures for future nanotechnology applications.
