Octakis(hydridodimethylsiloxi)silsesquioxane (Q8M8H) was synthesized and Ferrocene was adsorbed in a polymeric net through electrostatic interactions, with anion forming after the cleavage of any siloxy groups (ESFc). The nanostructured materials (Q8M8H and EsFc) were characterized by Fourier transform infrared spectra (FT-IR), nuclear magnetic resonance (NMR), X-ray diffraction (XRD), Thermogravimetric analyses and Voltammetric technique The cyclic voltammograms of the graphite paste electrode modified with ESFc showed one redox couple with E0′ = 0.320 V (1.0 mol L−1 NaCl, v = 50 mV s−1), with a diffusion-controlled process and the redox process shows electrocatalytic activity for the oxidation of ascorbic acid.
