In the present work, CT,namely 2,4,6-tris((9H-carbazol-2-yl)oxy)-s-triazine has been synthesized fromone step reaction of s-triazine and 2-hydroxycarbazole. Theelectropolymerization of POM/CT was carried out onto ITO-glass surface in 0.1 Mtetrabutylammonium hexafluorophosphate (TBAPF6)/acetonitrile (ACN)solution. The composite film displays enhanced electrochromic performance byincorporation of POM into the PCT film. The electrochromic and electrochemicalproperty of the composite film is significantly improved, which results in anoptical contrast of 59% at 670 nm and stability maintain 91% of its initialelectroactivity at the end of the 300 cycles. These results indicate the importantrole of POMs in improving optoelectronic properties of PCT to expandapplicationofelectrochromic devices.
