In this work, monomeric 3-([7]helicen-9-yl)thiophene was synthesized and used for the preparation of a polymeric film by electrosynthesis. The polymer prepared was characterized using Fe(CN) 6 3−/4− and Ru(NH 3 ) 6 3+/2+ redox probes, scanning electron microscopy and vibrational spectroscopy. The electropolymerization approach presented here provides a new option for the immobilization of helicenes onto solid supports.
