The structure and binding properties of a series of receptor molecules based on the building block diphenylglycoluril are described. These receptors bind dihydroxy-substituted aromatic guests in chloroform solution by means of hydrogen bonding and π-π stacking interactions. IR difference spectroscopy shows that the hydrogen bonds are formed between the OH groups of the guest molecule and the π-electrons
描述了一系列基于结构单元二苯基甘脲的受体分子的结构和结合特性。这些受体通过氢键和 π-π 堆积相互作用在氯仿溶液中结合二羟基取代的芳香客体。红外差分光谱表明,客体分子的OH基团与受体中存在的脲羰基的π电子之间形成氢键。通过将 1 H NMR 光谱中的络合引起的位移与主客体复合物的许多几何形状的计算位移进行比较,进一步研究了复合物的结构。这些数据表明客体分子被夹在受体的空腔内
