Electrochemical impedance spectroscopy of poly {pyrrole-trans-[(RuCl_2(pmp)_4]} copolymer films deposited on platinum electrodes

摘要

The present study focuses on the electronic and electrochemical features of a copolymer electrochemically grown from pyrrole and trans-[RuCl_2(pmp)_4] monomers, where pmp=3-(pyrrol-1-ylmethyl) pyridine. The results from electrochemical impedance spectroscopy analyses revealed the redox behavior of the poly {pyrrole-trans-[RuCl_2(pmp)_4]} compound as well as the non-homogeneous nature of the extremely thin polymeric layers. An equivalent circuit is proposed for an optimized film produced under the scope of the work.
