, p. 832 - 837 (2007/10/03)
The longest molecular ribbons known to date (3-10), composed of a series of metacyclophane units, have been synthesised by means of a repetitive synthetic strategy.These multiple ring systems with up to nine bridged benzene rings in a row are the lon

The hitherto longest molecular ribbons (4 - 6), composed of several metacyclophane units, are synthesized using a new iterative synthetic strategy, up to a length of seven fourfold-bridged benzene rings, and it is proved by X-ray crystal structural a

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. - Key Words: Azaphanes / Cyclophanes / Macrocycles / Molecular belts / Multistep strategy
