摘要 合成了一1, 4二环己基取代六元瓜环(DCYQ[6] )与硝酸锶形成的配合物,其结构为单晶X-射线衍射方法所确定。在此自组装结构中,一个DCYQ[6]分子包结一个硝酸个阴离子,而在DCYQ[6]的两羰基极性端口又与两锶离子作用形成一分子胶囊结构,而这些分子胶囊间又通过氢键自组装形成一维超分子结构。 A novel complex of a new 1,4-dicyclohexyl cucurbituril(DCYQ[6]) with strontium(II) ion was synthesized, and the crystal structure was determined X-ray diffraction. In this self-assembled entities both the cavity interaction of DCYQ[6] included a nitrate anion and the portal interaction of the dipole carbonyls of DCYQ[6] with strontium cations lead to form self assembled molecular capsules. The crystal structures of the entity show a 1D supramolecular structure of the self assembled molecular capsules connected by hydrogen bonds of water molecules.
