Thermodynamics of halogen bonded monolayer self-assembly at the liquid-solid interface

Mono layer self-assembly of a hexabrominated, three-fold symmetric aromatic molecule is studied at the heptanoic acid-graphite interface. Thermodynamical insights are obtained from an adapted Born-Haber cycle that is utilized to derive the overall enthalpy change including solvent effects. Comparison with theoretical entropy estimates suggests a minor influence of solvation.
