Jeong, Jaemyeng published the artcileSynthesis and characterization of triphenylamine-based polymers and their application towards solid-state electrochromic cells, Recommanded Product: 2,5-Dibromo-3,4-dinitrothiophene, the publication is RSC Advances (2016), 6(82), 78984-78993, database is CAplus.
Four novel triphenylamine-based polymers, PJK1, PJK2, PJK3 and PJK4 were successfully synthesized and fully characterized by 1H NMR, UV-VIS spectroscopy, cyclic voltammetry (CV), GPC and spectroelectrochem. These polymers are easily soluble in many common organic solvents, which make them appropriate for film deposition via spray-coating. We fabricated electrochromic cells comprising ITO-coated glass/polymer/gel electrolyte/ITO-coated glass and patterned the color change by applying d.c. with different voltages. We report herein color changes, from the neutral to oxidized form as follows: for PJK1, orange to dark green; for PJK2, light yellow to reddish brown; for PJK3, light blue to gray; and for PJK4, green to bluish green. The majority of the copolymers exhibited very good thermal stabilities, as evidenced by less than a 5% weight loss in temperatures exceeding 400°C. To further characterize, we simulated the electrochem. and optical properties, which are good agreement with the exptl. data.
