A three dimensionally ordered macroporous film of poly(3,4‐ethylenedioxythiophene) (3DOM PEDOT) has been electropolymerized from an ionic liquid, 1‐butyl‐3‐methylimidazolium hexafluorophosphate. Bragg diffraction of the highly ordered microstructure shows full‐color light reflection, and the color changes with a slight change in the angle of incident white light. In electrochromic studies, the 3DOM PEDOT film exhibits high transmittance modulation, high ionic fast switching speeds, and good cycling stability. The 3D interconnected macroporous nanostructure is beneficial for fast ion and electron transport, high ion accessibility, and structural integrity, resulting in high cycling stability and fast switching.
