| 英文摘要 | Bis-p-phenylene-34-crown-10 derivatives 1 and 2, bearing one and two dibenzo [24] crown-8 units, respectively, and 4,4'-dipyridinium derivatives of 3.3PF(6) and of 4.4PF(6), bearing one and two ammonium groups, respectively, have been synthesized from readily available starting materials. H-1 NMR and UV-vis studies reveal that in polar acetonitrile 1 binds 3.3PF6 to produce pseudo [2]rotaxane 1.3.3PF(6) by making use of one donor-acceptor and one electrostatic interaction, whereas 2 binds 4-4PF(6) to form pseudo [2] rotaxane 2.4.4PF(6) through one donor-acceptor and two electrostatic interactions. The association constants of the two pseudorotaxanes have been determined by the UV-vis titration method to be 9.1 (+/-1.0) x 10(3) M-1 and 6.5 (+/-0.7) x 10(5) M-1, respectively. The high stability of the new pseudo [2]rotaxanes has been ascribed to the cooperative interaction of the two different non-covalent forces. (C) 2004 Published by Elsevier Ltd. |
