Abstract

A convenient and higher yielding synthetic route to N-alkyl-bis(thiophene)- and N-alkyl-bis(ethylenedioxythiophene) carbazole derivatives is reported and their aggregation, and electrochemical properties are characterized. The key step in the synthesis of this group of compounds has been the Stille-type coupling reaction between the N-alkyldibromocarbazole and tin derivatives of thiophene or ethylenedioxythiophene, as the best way for preparation of conjugated N-alkylcarbazole derivatives. For this group of compounds we also present an electrochemical polymerization effect.
