Surface molecular self-assembly is an effective method to use relatively weak interactions such as hydrogen bonding, metal-ligand coordination and van der Waals forces, to form ordered molecular structures. Molecular assembly structures with the features of monolayer or sub-monolayer molecular thin films, have not only provided insight into intermolecular interaction forces, but also the possibility to adjust surface properties and functions. This research field has drawn wide attention and interest into control over the formation of covalent oligomers and polymers.
On-surface chemistry, also known as on-surface covalent reaction, has been a research focus of surface science owing to its characteristics of constructing covalently connected molecular structures. Most surface molecular covalency chemistry is conducted on surfaces of metal single crystals for the fabrication of macromolecules and polymers with precise, controllable and stable structures through intermolecular or intramolecular coupling reactions. The involved elementary reactions can be realised in traditional chemical synthesis, but the reaction pathways and products may be completely different from that in traditional reactions. The surfaces has inherent characteristics such as two-dimensional/one-dimensional spatial confinement, different adsorption sites, and thus has provided an important and unique avenue to the control over chemical selectivity, precise preparation of nanostructures.
