novel halogen bonding (XB) heteroditopic receptor are delineated via extensive cation, anion and ion-pair 1H NMR titration investigations. Through the contrasting size-dictated alkali metal cation binding modes of the XB receptor, these results serve to highlight the importance of combining allosteric preorganisation, electrostatics and XB potency to maximize enhancement of halide anion binding affinity
通过广泛的阳离子、阴离子和离子对1 H NMR 滴定研究,描述了新型卤素键合 (XB) 异二位体受体识别碱金属卤化物离子对的协同机制。通过对比 XB 受体的大小决定的碱金属阳离子结合模式,这些结果有助于强调结合变构预组织、静电学和 XB 效力以最大限度地增强金属前阳离子络合 XB 受体的卤化物阴离子结合亲和力的重要性。
