摘要：

A novel triptycene-derived bis-macrotricyclic host was designed and synthesized. The host was shown to form a 1:4 stable complex with 4 equiv. of dibenzylammonium salt in solution and in the solid state. Moreover, it was found that the host with multicavities could also self-assemble with 2 equiv. of bis-secondary ammonium salt to form a handcuff-like structure under the tested condition ([1](0) = 3.0 mM). The complexation and decomplexation of the assembly could be further chemically controlled by the stimuli of acid and base.
