Various supramolecular interactions have been explored for the growth of highly-ordered organic molecules at metal surfaces. An understanding of how these interactions balance with molecule � substrate interactions is essential to developing rational design rules for supramolecular architectures at surfaces. Here, we present results from scanning tunneling microscopy studies, couples with high-resolution electron energy loss spectroscopy, which allows insight into vibrational modes and structure, as well as X-ray photoelectron spectroscopy, which provides chemical information about the surface. This will include several examples of the interactions between small organic species at metal surfaces, as well as transitions to different chemical states and new structures in the second layer. This raises questions about the character of the first few layers at the organic / metal interface, which is essential for charge transfer and energy level alignment in organic devices.
