Covalent and Non‐covalent Attachment and Patterning of Polypyrrole at Silicon Surfaces

Abstract

DNA and alkenyl pyrrole functionalized silicon surfaces allow for the formation of silicon/polypyrrole junctions. These junctions are spatially controlled by photolithography (see Figure) and selective photo‐assisted electro‐oxidation of pyrrole. This process shows promise for use in the development of molecular‐based electronic devices, and could enable the deposition of polypyrrole analogously to metal ions in the formation of metallic wires.
