Abstract

The role of intermolecular interactions, molecule-substrate interactions and molecular chirality in the construction of 2-D surface architectures is the subject of much current interest. A racemic mixture of long chain hydrocarbons was synthesized with terminal carboxylic acid functionalities at each end, two amide linkages in the central region of the molecule either side of two F-containing chiral centres. Using Scanning Tunnelling Microscopy (STM), we have examined how the functionality of these molecules influences their self-assembly on an HOPG surface. The key factors determining the nature of ordered domains have been identified.
