| 摘 要： | Introduction The cucurbitn]urils (CBn]s) are a kind of cyclic methylene-linked glycoluril oligomers and possess a characteristic annular shape, with two identical car-bonyl-fringed portals.1-3 As the most common cucurbi-turil, CB6], has been widely studied in supramolecular chemistry by the groups of Mock4 and Kim.5 Recently, other CBn] (n=5, 7, 8), the molecular recognition properties of which are different from those of CB6] itself, have been extensively utilized in molecular rec-og…

| Abstract: | The first supramolecular adduct (H3O)2Cu(H2O)4](SO4)2?(C30H30N20O10)?4(H2O) based on cucurbit5]uril was synthesized and characterized by single crystal X-ray diffraction analysis. In the adduct, copper ion is coordi-nated by four oxygen atoms from H2O. The latter links two cucurbit5]uril molecules due to a complicated hydro-gen bonding containing lattice water molecules. |
