Preparation of Conjugated Polymers Inside Assembled Solid‐State Devices

Soluble precursor polymers are processed and assembled into solid-state devices and subsequently converted in the devices to conjugated electrochromic materials. This method, termed in situ conversion, requires no rigorous cleaning step for the electrode substrate. It eliminates the use of a costly electrolyte bath during the assembly process. This methodology results in high yields for the resultant conjugated system.
