![]() This methodology can therefore help to identify appropriate precursor molecules for forming target nanomaterials via bottom-up fabrication.īottom-up fabrication, which refers to the spontaneous formation of new materials via self-assembly of molecule precursors, is a way to create low-dimensional nanomaterials with atomic-scale structural precision 1, 2. ![]() By applying this method to the case of functionalized bianthracene precursors adsorbed to copper(111), we identify the functional groups needed to assemble one-dimensional chains, two-dimensional tilings, and other shapes. Application of this method produces a visual output (a dendrogram) that functions much like the periodic table, but whereas the periodic table puts atoms into categories according to the way in which they bond to each other, the dendrogram put molecules into categories according to the way in which they arrange in a self-assembled structure. Here we present an informatics technique which connects self-assembled structures with particular chemical properties of the precursor molecules. For bottom-up fabrication to succeed, precursor molecules which correctly assemble into the target structure must be first identified. Bottom-up fabrication via on-surface molecular self-assembly is a way to create defect-free, low-dimensional nanomaterials. ![]()
