Polymer films substituted with an appropriate receptor units represent a way leading to novel materials for a sensor development. Synthesis and characterization of solid-supported polymer and copolymer films based on a pyrrole-substituted binaphthalene amide (BNA). BNA was prepared by electropolymerization. The films were characterized by potentiometry and FT-Raman spectrometry. They showed a distinct potentiometric response to anions (F–, SO42–, Cl–). The potentiometric sensitivity of copolymer films depended on the BNA/pyrrole ratio in the polymerization and time of polymerization. The potentiometric results indicate the special role of the NH group during formation of the anionic potentiometric signal.
