a Schematic view of the preparation of spin-coating thin film on ITO/glass using CH3OH solution of polyOsRuFe-OAc. b Schematic representation of the three-electrode electrochemical measurement setup; polyOsRuFe-OAc/ITO/glass as WE, a platinum wire as the CE, and Ag/Ag+ as the reference electrode (RE). c Actual view of the three-electrode electrochemical cell with a side panel showing photographs of the film (1 cm × 1 cm) at different applied potentials. Side bar: the mechanistic view of the polymer for the color change is shown schematically. d In situ UV–vis spectra of a polyOsRuFe-OAc film on ITO/glass at different applied potentials of 0.70, 0.85, and 1.20 V for stepwise oxidation of Os(II), Fe(II), and Ru(II), respectively.
