Star-shaped dendritic molecules based on carboxylated carbazole and pyrrole as peripheral oxidizable units

The synthesis and spectroscopic characterization of three tricarboxylated pyrrole (Pyr)- and carbazole (Cbz)-containing star-shaped dendritic molecules 1-3 have been described here. Clauson-Kaas, amide coupling and debenzylation reactions have been used as key chemical tools. Electropolymerization of these oxidizable molecules has been investigated. The carboxylated Cbz-based molecules upon oxidative electropolymerization produced stable electroactive polyCOOH polyCbz films. (C) 2011 Elsevier B.V. All rights reserved.
