Charge‐Specific Interactions in Segmented Conducting Polymers: An Approach to Selective Ionoresistive Responses

Abstract

Charged with hopping: A conducting polymer containing electroactive segments interconnected by crown ether calix[4]arene units (see picture) exhibits dramatic changes in its conductivity in response to the binding of ions. There is over three orders of magnitude difference in conductivity between the incorporation of K+ and Ca2+ ions. The electrical conduction is best considered to be by a hopping mechanism.
