For self-assembly at the liquid/solid interface, the liquid phase acts as a reservoir of dissolved species which can diffuse towards the substrate, adsorb, diffuse laterally and desorb. These dynamic processes are highly sensitive to changes of the exact experimental conditions (solute concentration, choice of the solvent, deposition temperature etc.) and are on par with the proper supramolecular design for the formation of high quality monolayers at the liquid/solid interface. To get insights into the kinetics and thermodynamics of various processes occurring in surface self-assembly, we have studied bicomponent model systems based on dehydrobenzo[12]annulene (DBA) derivatives in which carefully designed marker molecules not only facilitate STM identification and analysis but also induce chirality and have well defined adsorption energies relative to the reference component. Here we report our preliminary findings on the effect of temperature and solution composition for the adsorption/desorption dynamics and monolayer growth in these systems.
