| Abstract
| - The self-assembly of cyanuric acid into ordered nanostructures on a crystalline substrate, highly orderedpyrolytic graphite (HOPG), has been investigated at low temperature under ultrahigh vacuum (UHV) conditionsby means of scanning tunneling microscopy in conjunction with theoretical simulations. Many domains withdifferent self-assembly patterns were observed. One such domain represents the formation of an open 2Drosette (cyclic) structure from the self-assembly process, the first observation of this type of structure forpure cyanuric acid on a graphite substrate. Each self-assembled domain exhibits characteristic superstructuresformed through different hydrogen bond networks at low coverage and low deposition rate. Experimentalobservation of coexistent, two-dimensional crystalline structures with distinct hydrogen bond patterns issupported by energy minimizations and molecular dynamics calculations, which show multiple stable structuresfor this molecule when self-assembled on graphite.
