Abstract: A new asymmetric functionalized star shaped triazine derivative, namely 2,2'-((6-(quinolin-8-yloxy)-1,3,5-triazine-2,4-diyl)bis(oxy))bis(9H carbazole) (TQC) was synthesized from 2-hydroxy carbazole and 8-hydroxyquinoline. The electrically conductive PTQC film was synthesized via electropolymerization on ITO in a 0.1 M lithium perchlorate/acetonitrile (LiClO4/ACN) electrolyte-solvent couple. 1H-NMR, FTIR and elemental analysis were used to analyze the structure of the TQC. Both electrochemical and spectroelectrochemical studies of the polymer were examined. PTQC revealed color changes between transparent and dark green in the reduced and oxidized states, respectively. Dual type polymer electrochromic devices (ECDs) based on PTQC and poly(3,4-ethylenedioxythiophene) (PEDOT) have been constructed. A potential range of 0 to 2.5 V was found to be proper for working the PTQC/PEDOT device between transparent and blue colors. The spectroelectrochemistry, electrochromic switching, open circuit memory and stability of the device were studied. The properties of the electrochromic device have been investigated such as spectroelectrochemistry, electrochromic switching, stability and open circuit memory.
