ability to complex halides and perchlorate has been studied in the solid state by X-ray crystallography. The results reveal that the ligands generally act as ditopic halide receptors with even the largest, L5, being too small to envelop the anion. The ligand's basicity behaviour parallels that observed for related para-analogues. Despite the ready crystallisation of fluoride, HF2-, chloride, bromide
已经研究了通过甲苯磺酰化的前体的二极偶合制备的五个大环多氮杂氮杂环烷L1-L5。配位体的碱度已通过电势法进行了测量,并且已通过X射线晶体学研究了其在固态下络合卤化物和高氯酸盐的能力。结果表明,配体通常用作二位卤化物受体,即使最大的L5也太小而无法包埋阴离子。配体的碱度行为与相关对位类似物所观察到的相似。尽管固态的氟化物,HF2-,氯化物,溴化物,碘化物和三碘化物盐易于结晶,但在电位计可访问的pH范围内,对水溶液中的卤化物似乎没有亲和力。
