Abstract

In the context of low cost flexible display device technology, requirements can be fulfilled with accessible multi-colored electrochromic polymers. Here, we report the synthesis and electrochromic properties of two spray processable, ambipolar, fluorescent and multi-color to transmissive electrochromic polymers. Polymers, PTBTPh and PTBTTh, have multi-colored oxidation states and easily accessible n-doped states, which allowed us to achieve transmissive films in a low working potential. Electrochemical and spectral results showed that both polymers are potential materials for electrochromic display devices.
