Electrochemical characterization of dissolved poly(N-alkylcarbazole) and charge transfer complex of carbazole derivatives

The aim of this work was to deal with the reductive chemical synthesis of s oluble poly(N-alkylcarbazole) (PCZ) derivatives. The polymers obtained were fractionned by successive solubilization in order to increase the molecula r mass and to decrease the polymolecularity. Furthermore fractionned polyme rs present a good electrochemical reversibility and cyclability. Charge transfer complex (CTC) were formed between poly(N-butylcarbazole) Pb uCz or 9,9' diethyl 3,3' dicarbazyl DEC and organic electron accepters such as TCNE, TNF were characterized by optical spectroscopy and differential s canning calorimetry.
