Abstract
A 3,5-bis((2-iodophenyl)ethynyl)pyridinium scaffold was synthesized which introduces the use of methanesulfonyl withdrawing groups to polarize iodine halogen bonding units for anion binding. We investigate the capability of this receptor to bind halides in polar media, while further probing the structure-property relationship of this well-polarized yet under-explored halogen bonding system.
摘要
我们合成了一种 3,5-双((2-碘苯基)乙炔基)吡啶翁骨架，该骨架引入了甲磺酰基吸电子基团，以极化碘卤键单元用于阴离子结合。我们研究了该受体在极性介质中结合卤化物的能力，同时进一步探讨了这个极化但研究不足的卤键体系的结构-性能关系。
