Combination of different chemical surface reactions for the fabrication of chemically versatile building blocks onto silicon surfaces.
The use of nucleophilic displacement reactions on bromine-terminated monolayers is presented to create new functional moieties onto silicon surfaces. Functional amines were used as suitable nucleophiles to introduce versatile building blocks onto self-assembled monolayers to perform further surface chemistry toward the fabrication of surfaces with designed properties by combining compatible chemical routes. These modified substrates were analyzed by suitable surface sensitive techniques. Furthermore, the functional monolayers were used for different postmodification reactions. For example, functional amines facilitated with acetylene groups were applied in the click chemistry approach. The use of amino-functionalized terpyridine units leads to the construction of supramolecular systems, where the choice of the metal monocomplex for the complexation is important for the tuning of the surface properties.
