New materials bearing thiophene and helicene moieties were prepared by using a potential‐driven on/off switch strategy on the surface of glassy carbon and indium tin oxide substrates. Specifically, a 3‐([7]helicen‐9‐yl)‐thiophene hybrid monomer was electrooxidized in acetonitrile by using cyclic voltammetry with anodic potential limits of +1.5 or +2.5 V, resulting in a conductive and non‐conductive polymer, respectively. The electrochemical findings were supplemented by microscopy investigations, UV/Vis, fluorescence and vibrational spectroscopies, and 1 H NMR spectroscopy as well as ellipsometry measurements and computational chemistry. The electrodeposited polymers could be used for the further development of materials applicable in organic electronics, optoelectronics, and sensing technologies.
