In my study, we use Suzuki coupling reaction to forming a series of triphenylamine-based monomers that have sulfonate segment in the side chain. Due to the sulfonate segment inside, we can add surfactant in solution to let molecules become nanomicelles. The other is triphenylamine group can be polymerized by electropolymerization and so we use this method to obtain conducting microporous polymer films with nano-sized. Because the films have electrochromic properties, we use it to black electrochromic device, which is rarely reported so far.
