Bernd Tieke and co‐workers ( p. 959 ) have created incredibly thin films that change color in response to an electric current. The electrochromic films were self‐assembled with zinc ions and polytopic polyiminofluorene‐tpy ligands and can be switched between yellow, red, and blue; they exhibit switching times of 450 ms, and display high contrast and high stability. The cover shows the process of coordinative self‐assembly and electrochromic switching, the background indicates the film surface.
