Abstract
This letter reports a new electrochromic polymeric film system consisting of a polymer, an electrochromic (EC) dye which is pyrazoline or tetrathiafulvalene (TTF), and lithium perchlorate (LiClO4). The electrochromic cell structure is glass/ITO/polymeric EC film/Au film. The cell using pyrazoline as an EC dye exhibited yellow coloration at 1.0 V and the cell with TTF exhibited red coloration at 3.5 V. These cells exhibited memory.Keywords
