Self-organization is the key. A series of dendritic pseudorotaxanes were efficiently constructed from complementary building blocks-namely, a three-armed, triply charged ammonium salt and the first, second, and third generations of benzyl ether dendrons bearing the dibenzo[24]crown-8 moiety. The pseudorotaxane arising from the third-generation dendron is shown in the picture.
