Pagination or Media Count:
We have developed new routes to prepare a series of derivatized electron-rich carbazole polymers containing polar ion transport, solubilizing, and redox active pendant substituents providing both multiple redox and multiple color states for electrochromic coatings. A series of electroactive electrochromic and electroluminescent conjugated polyelectrolytes based on 1,4-phenylene and 2,5-thienylenen linkages and containing both sulfonate and ammonium ion derivatized have been prepared. These polymers have been used in layer-by-layer electrostatic deposition processes for the preparation of electrochromic coatings, along with LEDs.
