Compound 7 exhibits a chiral helical structure, in which two CBBC subunits with the same configuration share a biphenyl unit. The twisting angle between the two phenylphenyl linkages at both ends is very large (270°) despite their short distance (6.2 Å), thus creating a short pitch (8.3 Å). Compounds 6 and 7 represent the first examples of nonplanar aromatic macrocycles that comprise two or more figure-eight subunits. These highly distorted structures can be expected to be difficult to construct via conventional bottom-up approaches.
