Abstract
Two homopolymers (poly(indole-6-carboxylic acid) (PInc) and poly(2,2′-bithiophene) (PbT)) and a copolymer (poly(indole-6-carboxylic acid-co-2,2′-bithiophene) (P(Inc-co-bT))) are electrodeposited on ITO electrode surfaces via electrochemical method. Electrochemical and electrochromic properties of PInc, PbT, and P(Inc-co-bT) films were characterized using cyclic voltammetry and in situ UV-Vis spectroscopy. The anodic P(Inc-co-bT) film prepared using Inc./bT = 1/1 feed molar ratio shows high optical contrast (30% at 890 nm) and coloring efficiency (112 cm2 C−1 at 890 nm). P(Inc-co-bT) film revealed light yellow, yellowish green, and bluish grey in the neutral, intermediate, and oxidation states, respectively. Electrochromic devices (ECDs) were constructed using PInc, PbT, or P(Inc-co-bT) film as anodic layer and PEDOT-PSS as cathodic layer. P(Inc-co-bT)/PMMA-PC-ACN-LiClO4/PEDOT-PSS ECD showed high ∆T (31%) at 650 nm, and PInc/PMMA-PC-ACN-LiClO4/PEDOT-PSS ECD displayed high coloration efficiency (416.7 cm2 C−1) at 650 nm. The optical memory investigations of PInc/PMMA-PC-ACN-LiClO4/PEDOT-PSS, PbT/PMMA-PC-ACN-LiClO4/PEDOT-PSS, and P(Inc-co-bT)/PMMA-PC-ACN-LiClO4/PEDOT-PSS ECDs exhibited that ECDs had adequate optical memory in bleaching and coloring states.
