Self-assembly of molecules on surfaces directed by different supramolecular interactions has been widely explored. There are striking examples of molecular surface structures, whose formation is driven by metal co-ordination[1], dipolar coupling[2] or hydrogen bonding[3] interactions. In contrast to these examples, our aim is the formation of covalently linked planar structures by means of poly...
