crystal lattice. In the presence of anion guests or solvent molecules with competing hydrogen bond donors and acceptors, other supramolecular arrangements can be observed. Solution studies conducted in DMSO-d6/0.5% H2O by means of 1H-NMR titrations show the formation of 1:1 adducts with all receptors. The different observed affinities of the receptors for the anion guests were rationalised in terms of
摘要在此,我们报告了 N,N'-二苯基脲 L1-L15 家族的合成和阴离子结合特性,该家族带有芳香环卤素(氯和碘)和/或硝基或三氟甲基吸电子基团. 对从单晶 X 射线衍射实验获得的晶体结构的分析表明,通过 N-H···O 氢键连接的自组装链或带是此类分子在晶格中最常用的排列方式。在阴离子客体或溶剂分子与竞争性氢键供体和受体的存在下,可以观察到其他超分子排列。通过 1H-NMR 滴定在 DMSO-d6/0.5% H2O 中进行的溶液研究表明,所有受体都形成了 1:1 的加合物。
