摘要：

Thin functionalized polypyrrole films exhibiting cation-exchange ability have been synthesized by oxidative electropolymerization of a pyrrole-carboxylic acid monomer on indium tin oxide (ITO) electrodes. The incorporation of hexaamineruthenium, tris(1,10-phenanthroline)iron and 5,10,15,20-tetrakis(1-methyl-4-pyridyl)-21H,23H-porphyrin cations was easily achieved in preformed films. Results from these incorporation experiments allowed the determination of the pK(a) of the polymeric material and its exchange capacity. The latter was estimated at 4.5 molar equiv. kg(-1), which is comparable to those of regular cation-exchange resins.
