A tetra-armed cyclen () with two substituted 3,5-difluorobenzyl and two substituted pyridine-4-yl methyl groups at the 1,4- and 7,10-positions of the cyclen ring as side arms was synthesized. When was reacted with 1 equiv of the silver(I), dimetallo[3.3]paracyclophane-like 2:2 cyclic dimer, Ag(), was obtained. The reaction of with 2 equiv of silver(I) gave a 3:6 cyclic trimer, Ag()(CHCN)·3CHCN. Furthermore, reversible complexation between the 2:2 cyclic dimer and 3:6 cyclic trimer was confirmed by H NMR and the CSI mass in the addition of silver(I) or the [2.2.2]cryptand.
合成了一种四臂环糊精（），在环糊精环的1,4 - 和7,10 - 位带有两个取代的3,5 - 二氟苄基和两个取代的吡啶 - 4 - 基甲基作为侧链。当与1当量的银（I）反应时，得到二金属[3.3]对环芳烷样的2:2环状二聚体Ag()。与2当量的银（I）反应得到3:6环状三聚体Ag()(CHCN)·3CHCN。此外，通过1H NMR和在添加银（I）或[2.2.2]穴醚时的CSI质谱证实了2:2环状二聚体和3:6环状三聚体之间的可逆络合。
