In the Concept article on page 16696 ff., T. Shoji and S. Ito discuss the synthesis of azulene‐substituted 1,1,4,4‐tetracyanobutadines connected with various π‐electron system, which were prepared by formal [2+2] cycloaddition–retroelectrocyclization of alkyne derivatives with tetracyanoethylene, as well as their optical and electrochemical properties. The formation of furan derivatives under similar reaction conditions is also described. Emphasis is placed on the reversibility and significant color changes of these derivatives under the electrochemical redox conditions.
