Abstract :

The compound containing carbazole and thiophene, named as B1 was synthesized with 4- (9H-carbazol-9-yl) phenol and 3, 4-dibromo thiophene. Additionally, the electrochemical polymer of B1 was synthesized and coated onto an ITO-glass surface via electrochemical oxidative polymerization. The electrochemical synthesis of the polymer was performed both in 0.05 M LiClO4 supporting electrolyte in AN/BF3EtE (1:1, v/v) and an AN/LiClO4 solvent/electrolyte solution. The spectro electrochemical and electrochromic properties of this polymer were also investigated for two electrolyte solution systems. The switching ability of this polymer was measured as the percent transmittance (%T) at its point of maximum contrast. According to the electrochromic measurements, the synthesized polymer had a blue color when it was oxidized, and also when it was reduced, it had a transparent color. Additionally, redox stability measurements indicate that the polymer had a high stability and it could be used to produce new polymeric electrochromic devices. The in situ polymerization kinetics related to the synthesized polymer was performed. According to this process, a constant potential of +1.2 V was applied to the polymer film by performing an absorbance measurement for per 10s. resultantly, it can be said that it is a good candidate for electrochromic devices (ECDs) applications. Additionally, it is suitable for the electrochromic display with relatively low potential (+1.2 V) due to the switching ability of this polymer.
