英文摘要: A variety of novel calix[4]arene-incorporating crown ethers with or without intramolecular hydrogen bonding have been prepared by two efficient methods and utilized as donor rings to assemble calix-[4]arene [2]catenanes based on s-stacking interaction between hydroquinone and bipyridinium units. Treatment of calix[4]arene crown ethers 4, 10a, or l0b, whose cone conformation was fixed by intramolecular hydrogen bonding within the calix[4]arene moiety, with dicatlonic salt 15.2PF^6 and dibromide 16 afforded the corresponding [2]catenanes 17a’4PF^6, 17b4PF^6, and 17c4PF^6 in 20%, 53%, and 55% yields, respectively, whereas from the reactions of 15.2PF^6 and dibromide 16 in the presence of conformationally flexible 11 or 12 with a cone conformation kept by two propyl groups. [2]catenanes 18.4PF^6. And 19.4PF^6 were obtained in 12% and 6% yields. [2]Catenanes 21a 4Cl, 21b.4Cl, and 21c.4Cl, incorporating calix[4]arene in both the donor and acceptor rings, were also successfully assembled from lOa or lOb, 16, and dicationic salts 2Oa.2PF^6 or 2Ob.2PF^66. The dynamic 1~H NMR and absorption spectra of the [2]catenanes have been investigated, which revealed a strongest donor—acceptor interaction in 17a.4PF^6 and that the cone [2]catenanes 17a—c.4PF^6 can isomerize to the partial cone isomer at high temperature. The difference of the dynamic properties of these catenanes was discussed. The results demonstrate that catenation is one new general method to change the conformational distributions of calix[4]arenes.
