High-density graft films bearing ferrocene (Fc) moieties were fabricated on quartz and indium tin oxide (ITO) substrates by surface-initiated atom transfer radical polymerization (ATRP). The thickness of the film increased with the increase in the molecular weight of the polymer. We successfully observed quantitative electrochemical redox signals on the ITO substrates coated with a graft polymer. The cyclic voltammograms showed that all ferrocene moieties were electrochemically active.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
