A π‐conjugated electrochromic polymer (ECP) with alkyl ester side‐chains is synthesized and subsequently defunctionalized to yield a polyionic salt readily soluble in water and further spray‐processable from water. Upon neutralization, the defunctionalized polymer backbone recovers its electrochromic properties. The ability to print‐ or spray‐process π‐conjugated ECPs from aqueous media offers a sustainable alternative to traditional organic solvent‐processing methods and could impact the development of non‐emissive flexible display technologies.
