摘要：
The dimerization of the self-complementary resorcarene tetraesters is triggered by the entrapment of a tropylium cation in the π-basic cavity. Eight intermolecular OH···OC hydrogen bonds together with host-guest interactions such as charge transfer and C-H···π bonding are responsible for the high stability of this assembly (see picture). Hereby neither the host-guest interaction nor the interaction of two resorcarene molecules through hydrogen bonds is sufficient by itself to form the complex.
