Hydrogen-Bond-Assisted π-Stacking of Shape-Persistent Cyclophanes

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