Hydrogen-bond-assisted pi-stacking of shape-persistent cyclophanes.
The pi-stacking interaction between shape-persistent cyclophanes works cooperatively with multiple hydrogen bonding sites to form cyclophane dimers. These findings considerably broaden the applicability of pi-stacking interactions as a driving force in self-assembly chemistry. A gel formation effect was also noticed in one of the cyclophanes.
