Abstract
The hitherto longest molecular ribbons (4–6), composed of several [3.3]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 analyses and 1H NMR spectroscopy that these molecules form meander-type folded syn conformations leading to multiple π-staples.Keywords
