摘要：

1,3,5-{Tris(3-n-butylimidazolio)methyl}-2,4,6-trimethybenzene 1, which has three imidazolium groups connected through a 1,3,5-trimethylbenzene spacer, has been synthesized as a novel receptor for halide anions. This tripodal receptor is shown to bind strongly Cl-, Br-, and I- anions in CD3CN through electrostatic interactions and C-H ... X- hydrogen bonds. (C) 1999 Elsevier Science Ltd.
