Figure 5
Perspective view of the polar molecular layers of (4) and (3) formed on the parallel helices along the b axis. The 18-membered homodromic (left) and antidromic (right) rings are shown in different colors. Apart from the five- and seven-membered rings, the patterns can hardly be distinguished from each other.
