In this paper, a novel secondary dialkylammonium salt with three stations (G1) was synthesized in 5 steps. 1H
NMR was used to study the threading of G1 through the cavity of dibenzo-24-crown-8 (DB24C8) and benzo-21-crown-7
(B21C7). The complexation of G1 and two crown ethers was proved to be slow-exchange systems. This result lays the
foundation on the integrative self-sorting organization of G1, DB24C8 and B21C7.
