anion receptors have been evaluated. The receptor with bis(trifluoromethyl)aniline groups has shown a very high affinity for halide ions, especially remarkable as only two hydrogen bonds are formed in the complexes. 1H NMR and fluorescence titrations have been carried out and binding constants up to 7.9 × 106 M−1 have been reached. X-ray structures have been obtained and a modelling study has shown the
咔唑已经合成了被两个磺酰胺基团官能化的基团受体,并评估了它们作为阴离子受体的性能。受体与双(三氟甲基)苯胺 基团对卤离子表现出很高的亲和力,特别是因为只有两个 氢在配合物中形成键。已经进行了1 H NMR和荧光滴定,并且达到了高达7.9×10 6 M -1的结合常数。已获得X射线结构,并且建模研究表明这些化合物对卤化物阴离子的亲和力大的可能原因。
