The self-assembly of small molecules at surfaces is a rapid, scalable and relatively inexpensive approach to the formation of two-dimensional molecular crystals with a range of interesting properties. We are working to understand the self-assembly of model molecules on a range of surfaces, with a particular focus on understanding the chemical reactions that self-assembled networks undergo with heating (e.g., transitions from hydrogen bonded to metal-coordinated networks).
To gain a detailed understanding of the chemistry and structure of these systems, we draw on a range of tools including scanning tunnelling microscopy (STM), x-ray photoelectron spectroscopy (XPS) and synchrotron-based photoelectron spectroscopy (PES) and near edge X-ray absorption fine structure (NEXAFS).
