| 4 | New Host Molecules with Imidazoliums as Functional Arms:Syntheses and Anion Recognition显示文摘The bridged tri-imidazoliums 3.3X^--5.3X^-(X^-=PF6^-,Br^-,I^-)and bis-imidazoliums 6.2PF6^- were synthesized by N-quaternization of imidazole derivative 1 in acetonitrile under reflux.UV spectroscopic titration experiments showed that the halide salts and hexafluorophosphate salts of these imidazoliums exhibited good recognition toward anions in water and in acetonitrile,respectively. | Yuan, Y Jiang, ZL Gao, G Zhang, GL You, JS Xie, RG | 2002 | Chinese Journal of Chemistry2002，20，5： | 0 |
