a CVs of a 0.2 mM solution of Fe5-PCz in dichloromethane containing 0.1 M TBAP under Ar at a scan of 100 mVs−1. WE: glassy carbon (GC); CE: Pt wire; RE: Ag/Ag+. CV scans are initiated from the open-circuit potential. b UV–Vis–NIR absorption spectra of ITO electrodes electrolysed at 1.17 V vs. Fc/Fc+ for 15–60 s in a 0.2 mM MeCN solution of Fe5-PCz containing 0.1 M TBAP. Photographs of the ITO electrodes after electrolysis (inset). c Square wave voltammograms of poly-Fe5-PCz@GC (red line) and Fe5-PCz (grey dotted line). Measurements were performed in γ-butyrolactone containing 0.1 M TBAP under Ar at a scan rate of 50 mVs−1. WE: GC, CE: Pt wire, RE: Ag/Ag+. d Fe L3-edge soft X-ray absorption spectra of poly-Fe5-PCz@GC (red line) and Fe5-PCz (grey dotted line).
