  Giant Cyclophanes Built from Polyphenyl Aromatic Substructures

  摘要：

  Two very large cyclophanes (3, C132H92O8S4; 4, C172H120O8S4) were prepared by means of short syntheses (similar to 5 steps) from commercial starting materials. In each of these cyclophanes, two octaphenylnaphthalene subunits or two 1,3-bis(pentaphenylphenyl)benzene subunits were tethered to form the final macrocycle. X-ray analysis of 3 shows it to have a collapsed conformation, but molecules of 4 have large central cavities which are aligned in the crystal to form wide, solvent-containing channels.
