Belt‐Shaped Molecules by a Repetitive Synthetic Strategy Belt‐shaped molecules of the general type 2 containing up to five benzene ring units (cf. 37 ) have been synthesized by macrocyclisation reactions of ribbon‐shaped precursors. An intermolecular cyclization step generates the macroheterocycles 38 and 40 . The fourfold‐bridged cyclophane 36 are prepared by intra‐and intermolecular cyclization reactions. The X‐ray structure analyses of 14, 16, 22, 23, 28 , and 36 show S‐shaped conformations of the molecules.
