In this CrystEngComm Hot Article, Johanna Eichhorn and colleagues from Munich, Germany study the self-assembly of melem on Ag(111) surface using scanning tunnelling microscopy.
They observe seven different monolayer polymorphs stabilized by intermolecular hydrogen bonds. Porous surface-supported supramolecular monolayers have potential applications as host networks for the inclusion of guests or even as organic templates for the growth of size-selected metal nanoparticles.
