Jacob Jensen, Aubrey L. Dyer, D. Eric Shen, Frederik C. Krebs and John R. Reynolds Direct Photopatterning of Electrochromic Polymers Advanced Functional Materials 23
Direct photopatterning of a conjugated electroactive dioxythiophene-based polymer is presented. Thin films of the polymer are spray-cast from organic solvents, followed by insolubilization via photocrosslinking. The crosslinking process does not cause any detriment to the electroactivity or optical properties of the polymer, which can be redox switched between a colored and bleached state, as desired for electrochromic displays and windows.
