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.
本文通过 5 个步骤合成了一种新型具有三个位点的仲二烷基
铵盐(G1)。利用 1H NMR 研究了 G1 穿过二苯并-24-
冠醚-8(DB24C8)和苯并-21-
冠醚-7(B21C7)空腔的过程。G1 与两种
冠醚的复合物被证明是慢交换体系。这一结果为 G1、DB24C8 和 B21C7 的整合自排序组织奠定了基础。
