Abstract
New crown-ether-functionalized alkyl(oligothiophene)s (see Figure) hav e been synthesized and electropolymerized to alkali metal ion sensitiv e poly(alkylthiophene)s. It is shown for the first time that the redox chemistry of a conducting polymer is strongly influenced by the speci fic host-guest interaction, although the crown ether units are not pi- conjugated to the conducting backbone but separated by an insulating o xa-alkyl chain.
