Figure 2
A depiction of the supramolecular pillars using a ball-and-stick model with standard CPK colors (I = purple). The left portion of the figure shows the pillars with a view that is aligned with the plane of the aromatic carbazole system, the right portion of the figure shows the same molecules tilted slightly along the b axis. The π–π interactions described in the text are depicted with purple dotted lines and the unit cell is drawn with a solid black line. |
