摘要：
In the structure of the title compound, C18H14O 2, the two benzene rings are inclined at an angle of 54.25 (13)°. The packing of the molecules is mainly governed by weak intermolecular C-H⋯O hydrogen bonds with no π-π stacking observed. © 2006 International Union of Crystallography All rights reserved.

摘要：
本文以二苯基甘脲为建筑模块合成得到一对不对称U型三维结构的拓扑异构体,该不对称分子夹在堆积过程中选择性形成一种异手性自组装二聚体AB1,这种对映选择性自组装主要是分子间CH…O和CH-π两种弱氢键协同作用的结果.其中,CH…O作用在手性识别中起着关键作用.

摘要：
The title compound, C30H36N6O6, is a glycoluril derivative with two ethyl acetate substituents on the convex face of the glycouril system. Two equivalent six-membered triazine rings bind the N atoms from separate rings of the glycouril unit to form the flexible sidewalls of a molecular clip. One N atom from each ring caries a 4-methylbenzyl substituent. The crystal structure is stabilized by intermolecular C—H⋯O interactions.

摘要：
The molecule of the title compound, C58H42N 4O6, a molecular clip based on the glycoluril framework, occupies a special position on a twofold axis passing through the mid-point of the gycoluril C-C bond. The planes of the central benzene rings in the opposite wings of the molecular clip form a dihedral angle of 41.6 (4)°. No dimers typical for molecular clip packings are observed in the crystal structure of the title compound. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.

摘要：
In the title glycoluril derivative, C18H28N6O8, the N - C-carbonyl bond distances are much shorter than the other N - C bond distances in the same five-membered ring, indicating electron delocalization within the nearly planar ring. Both six-membered rings display chair conformations.

摘要：
以拥有芳环边墙和酰胺侧链的C形双聚苷脲化合物为组装子时,若两两混合,有三种自组装堆积态存在:AA、BB、AB,但当酰胺侧链上的取代基R’为CH3与PhF5时,它们的自组装堆积态主要以杂化的AB形式存在。

摘要：
具有高度识别性的新型合成受体的构筑一直是主客体化学的研究热点[1],因为它们是人们借以模拟生物酶的复杂结合过程、了解酶与底物之间弱相互作用力(如疏水效应、π-π堆积、氢键等)的作用形态的桥梁分子[2,3].目前,对一些经典的受体,如环糊精、杯芳烃、葫芦脲等,都已进行过广泛而深入的研究,但由于这些受体的孔径较小,构造板块单一,从而限制了它们对客体分子识别的选择性和包结能力.我们在考虑和设计新的分子受体的结构时,期望以多样性的构造板块构造出拥有较大三维几何空腔的分子,从而提高受体的选择性和识别能力.……
