ADAPTNANO · Adaptive nanostructures prepared by hierarchical self-assembly

The aim of the project is a rational design of complex molecular self-assembled surface nanostructures the properties of which could be externally switched or their self-assembly process could be externally controlled. The project covers the research on the self-organization processes of molecules on metallic surfaces with ultra thin insulating layers and graphene substrates. Using the intermolecular bonds with graded strength the complex hierarchical architectures should be realized. The incorporation of switchable molecules gives the structures specific functional properties. The main idea lies in the preparation of nanopores which can be opened or closed through switching the molecules by light induced cis/trans isomeration which will be controlled by a proper choice of the used light wavelength. The detailed study of intermolecular interactions on insulating layers as well as understanding the light-induced switching processes in the nanostructures will be in centre of interest. Next, the influence of adjustable electronic density of graphene substrates or external electric fields on molecular self-assembly processes will be also studied.
