Abstract
The synthesis of new functionalized conducting polypyrroles bearing aza crown ethers of variable cage size at the 3-carbon atom of pyrrole is described. The electrochemical selectivity of these electropolymerized polymers towards cations has been analyzed in organic media using the alkaline series Li+, Na+ and K+. A selectivity towards Na+ and K+ is clearly evidenced and discussed in terms of cage size. This result brings an interesting example of transduction of a chemical information into an electrical signal.
