In this work the nature of the substitution process in the electrochemical deposition of different 4-substituted benzene layers on Au and the influence of the solvent were studied. We monitored the deposition from the corresponding isolated salt diazonium salts and

We report a novel route for the functionalization of any substrates, including chemically inert substrates. CVD grown graphene is electrochemically functionalized with p-(N-maleimido)phenyl residues and consecutively transferred to various substrates. The transfer process is shown to be without noticeable loss. The functional layer exhibits a thickness of appx. 4.5 nm.
