Abstract: Conjugated copolymers are provided that can be processed in a variety of solvents and can be rendered solvent-resistant when needed. The copolymers can be solution cast from nonpolar, polar, and aqueous solvents. After casting a polymer layer, the polymer can be rendered solvent resistant, thereby providing for improved stability and multi-layer processing and in electrochromic devices where the polymer layer is in contact with a nonpolar or polar solvent or electrolyte. Methods of making the copolymers are also provided, as well as methods of solution casting the polymers from a variety of nonpolar organic, polar, and aqueous solvents. Electrochromic devices are demonstrated having electrode(s) containing these polymers, including a variety of supercapacitor devices capable of using organic, biological, and aqueous electrolytes. Some of these electrodes demonstrate superfast switching and large power densities, showing promise for applications in supercapacitor batteries.
