Thiol-yne click chemistry post synthesis modification (PSM) is used to further functionalize a fully organic porous polymer coating (SURGEL). By cyclic voltammetry the resulting electrochemical properties are addressed. The Nernstian diffusion limited process observed in the presence of ferrocene as electrolyte is explained in terms of a high permeability of the SURGELs for ferrocene after PSM.
