AbstractPhotoswitchable stamp surfaces would allow a highly flexible and quick variation of the patterns formed by microcontact transfer printing. An attempt to synthesize the azobenzene 1-(4-hydroxy-3-(phenyldiazenyl)phenyl)-1H-pyrrole-2,5-dione proved unsuccessful. Discrepancies found in the paper this work was based on lead to an invitation by the editor of Molecules to publish a comment on the paper. As an alternative approach, the surface modification using an azobenzene containing dendron was investigated. A synthesized denron including a maleimide moiety gave broad 1 H-NMR-signals. A further dendron with an alcohol moiety at the focal point was successfully synthesized and characterized. PDMS functionalization was achieved with this dendron, however by adsorption into the elastomer.
