本研究成功的將苯基哌啶、苯基嗎啉、苯基亞氨基芪、苯基吲哚及1-萘醯胺連接於聚二噻吩一吡咯上，分別命名為PPPP、PPMP、PPIM、PPIN和PNAH。將五種陽極材料以電化學聚合法製成導電高分子薄膜，進行其光學及電化學性質之探討，包含光學對比值、顏色變化、光學穩定性和著色效率。在單電極測試中，陽極材料以PIM薄膜在液態電解質([EPI+][TFSI-])中，波長位於910 nm下具有最大穿透差值60.1%，最大著色效率高達208.22 cm2/C。PIM薄膜在液態電解質([EPI+][TFSI-])中，在中性態施加電壓至氧化態具有多種色彩變化。五種陽極材料(PPPP、PPMP、PPIM、PPIN或PNAH)與不同之陰極材料(PProDOT-Et2及PProDOT-Bz2)搭配組成三明治型式元件進行光譜電化學性質測試。在雙電極(元件)進行測試結果發現，以PNAH/PProDOT-Bz2元件位於波長580 nm下，具有最大穿透差值38.8%，和著色效率555.83 cm2/C。著色效率以PPIM/PProDOT-Et2元件最佳，於574 nm處可以達到879.08 cm2/C。以上提及的元件，光學記憶測試之穿透度變化值都只在1~6%內，組成元件後，不只轉換時間更短，著色效率也大幅提高。此外，本研究證實以上電致變色材料與元件皆有良好之光學對比及穩定性。

Phenylpiperidine, phenylmorpholine, phenyldibenzo[b,f]azepine, phenylindole and napthamide units are incorporated to pyrrole ring of polydithienylpyrroles, which are denominated as PPPP, PPMP, PPIM, PPIN, and PNAH, respectively. The optical and electrochemical properties of five anodically coloring polymers, such as optical contrast, color variations, optical stability, and coloration effiency are characterized. The ∆Tmax of PIM film is 60.1% at 910 nm, and the maximum coloration efficiency of PIM film is 208.22 cm2 C-1 at 910 nm in an ionic liquid ([EPI+][TFSI-]) solution. Moreover, dual type electrochromic devices (ECDs) employ PPPP, PPMP, PPIM, PPIN, or PNAH as anodic layer, and PProDOT-Et2 or PProDOT-Bz2 as cathodic layer are fabricated. The ∆Tmax and maximum coloration efficiency of PNAH/PProDOT-Bz2 ECD are 38.8% and 555.83 cm2/C at 580 nm, respectively. PPIM/PProDOT-Et2 ECD shows the highest coloration efficiency (879.08 cm2/C) at 574 nm. The transmittance variations of optical memory effect for all ECDs are less than 1~6%. ECDs show shorter switching time and higher coloration efficiency than those of polymer films. In addition, electrochromic materials and ECDs display satisfactory optical contrast and stability.
