Abstract
The control and organization of molecular species at interfaces is key to advance molecular science, nanochemistry and the development of novel materials. We explore the pertaining bonding, assembly and dynamic behaviour at well-defined homogenous surfaces, textured templates and sp2-sheet layers. The developed bottom-up fabrication protocols employ biological and de novo synthesized building blocks, exploiting error-corrective bonding schemes as well as covalent chemistry. Our approach provides a rationale for the interfacial control of single molecular units and the design of nanoarchitectures with remarkable structural features, intricate dynamics and tailored properties.
