Electrochemical synthesis and electrochromic properties of new conjugated polycarbazoles from di(carbazol-9-yl)-substituted triphenylamine and N-phenylcarbazole derivatives

摘要: Abstract Two carbazole end-capped monomers containing triphenylamine or N -phenylcarbazole as an interior core, namely 4,4′-di(carbazol-9-yl)-4″-methoxytriphenylamine (TPA-2Cz) and 3,6-di(carbazol-9-yl)- -(4-methoxyphenyl)carbazole (PhCz-2Cz), were prepared by a well-known chemistry from readily available reagents. The electrochemistry electropolymerization of these two investigated compared with those structurally similar analogs tert -butyl groups attaching on the active sites units. polymeric films built onto ITO/glass surface repetitive cyclic voltammetry (CV) scanning monomer solutions electrolyte. electro-generated polycarbazole exhibited high redox-activity strong color changes upon electro-oxidation, which can be switched potential modulation. remarkable electrochromic behavior film was clearly interpreted basis spectroelectrochemical studies, stability evaluated switching studies.
