Molecules of the TTF and TCNQ Type with Macrocyclic Skeletons The electron‐rich and electron‐poor macrocycles 1 – 3 have been synthesized. Their [1.1](3,3′)biphenylophane framework is formed by Kharasch reaction. Whereas in the well‐known donors and acceptors I – III the functionalities are conjugated, in their macrocyclic “analogues” 1 – 3 the conjugation is prevented by the meta ‐connection of the phenylene rings. The redox properties —studied by cyclovoltammetry — are discussed. The X‐ray analysis of 3 shows considerable deviations from a planar structure.
