The Cover Feature shows a dynamic color‐changing window constructed on transparent wood substrates. These substrates are mechanically robust, thermally insulating, and provide a diffuse transmittance of 80% over the visible region. The window is shown to be switching in four stages between a charged, color‐neutral state and a discharged, colored state. In this work, poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) treated with a mild acid was used as an electrode material to enable all‐polymer electrochromic devices that exhibit a vibrant color change at a low voltage (0.8 V), and optical memory for 3 h. More information can be found in the Full Paper by Lang et al. on page 854 in Issue 5, 2018 (DOI: 10.1002/cssc.201702026).
