Elaboration and characterization of new membranes based on the electropolymerization of mixtures of pyrrole and 4,4′-bis[N-(1-oxo)hexylpyrrole]dibenzo-18-crown-6 monomers Original Research Article

New membranes have been prepared by the electropolymerization of a new pyrrole dibenzo-18-crown-6 monomer with the pyrrole. The results present the characterization of the membrane recognition properties in the presence of different electrolytes. Films present a sensitivity to divalent cations like Ca2+, Mg2+ or Cu2+ owing to the crown ether function. Potentiometric measurements have allowed to quantify the membrane selectivity toward divalent cations in presence of Na+.
