摘要 用1HNMR滴定技术研究了吡咯 2,5 二乙酰胺衍生物1 4的阴离子配位性质.在氘代乙腈中,受体1 4是含氧阴离子的有效接受体,但在更具竞争性的氘代DMSO溶剂中,其对阴离子的亲和性要小得多. The anion binding properties of diamide derivatives of pyrrole-2,5-diacetic acid 1-4 were investigated, using ()~1H?NMR titration techniques. Compounds 1-4 are shown to be effective receptors for oxo-anions in acetonitrile-d_3 solution. However, they display reduced affinities for all the anions studied in a more competitive solvent, DMSO-d_6, as compared to the association constants measured in acetonitrile-d_3.
