AbstractCyclobis(paraquat‐p‐phenylene), also known as “blue box”, is a highly electron‐deficient macrocycle, widely used as a molecular receptor for small electron‐rich molecules. Inserting a reactive functional group onto the molecular structure of this cyclophane is paramount for its inclusion into complex architectures. To this aim, including an alkyne moiety would be ideal, because it can participate in click reactions. However, the synthesis of such alkyne‐functionalized cyclophane suffers from several drawbacks: the use of toxic and expensive CCl₄, the need for high‐pressure reactors, and overall low yield. We have revised the existing synthesis of this cyclophane derivative bearing an alkyne moiety, to overcome all these limitations. In particular, photochemical radical bromination is adopted to obtain a sensitive intermediate. We demonstrated that the synthesized host molecule can be functionalized via click reactions and take part in radical‐radical interactions. Our work makes a key functionalized paraquat macrocycle more accessible, facilitating the development of novel redox‐responsive systems.
