| In this contribution we present a facile yet versatile way for the functionalization of surfaces with ultrathin layers of covalently attached polymers. The overall process starts with the generation of a self-assembled monolayer of molecules carrying a photoreactive group (e.g. benzophenone). This monolayer is then covered with a polymer layer and irradiated with UV light. During illumination a photoreaction is triggered through which the benzophenone attaches to polymer chains in the vicinity leading to a surface attachment of these chains. Due to the rather unspecific nature of this reaction a wide variety of polymers can be attached to the surface including such that carry further reactive or functional groups. Especially in the latter case one can use this approach to generate sensor devices or to decorate surfaces with groups for molecular recognition. Examples for such systems and strategies for microstructuring will be presented. |
