Well-defined side-chain ferrocene-containing polymers have been synthesized by post-modification of well-defined polyacrylonitrile (PAN). PAN prepared by Cu(0)-mediated single-electron transfer living radical polymerization was further modified using sodium azide and ammonium chloride (NH4Cl) to yield polymeric materials with vinyltetrazole units. Side-chain ferrocene-containing polymer was prepared by vinyltetrazole units and hydroxymethylferrocene after Mitsunobu reaction. FTIR, 1H NMR, UV–Vis spectroscopy and thermogravimetric analysis were used to identify the structure of the target product. After linked the ferrocene unit, the final polymer showed typical redox property with a more negative redox potential (E1/2).
