Abstract: The present invention describes a method for producing a large area two-dimensional nanoscale network on the surface of a substrate. The network is formed by depositing a sub-mono-layer of molecule A onto the surface of the substrate followed by a different molecule B. The formation of the network relies on the hetero-molecular hydrogen bonding between molecules A and B to be stronger than the homo-molecular hydrogen bonding. By appropriate choice of molecules A and B, together with the substrate, it is possible to manipulate and control the structure, dimensions and chemical functionality of the network. The pores of the network can act as containment vessels for other molecules and be made sufficiently large to accommodate several large molecules or atomic/molecular clusters or particles.
