1，4二环己基取代六元瓜环与Na(Ⅰ)自组装实体的合成与晶体结构

A novel complex of a new 1,4-dicyclohexyl cucurbituril(DCYQ[6]) with sodium(Ⅰ) ion was synthesized, and the crystal structure was determined by X-ray diffraction technique. In this self-assembled entity both the cavity interaction of DCYQ[6] included a nitrate anion and the portal interaction of the dipole carbonyls of DCYQ[6] with sodium cations lead to form self assembled molecular capsules. The crystal structure of the entity shows a packing of the self assembled molecular capsules connected by hydrogen bonds of water molecules. CCDC: 271400.     

(R)-1，1′-联萘手性单元通过溶胶凝胶法合成杂化硅干凝胶(英)

Precursor molecule (R)-6,6′-bis(triethoxysilylethen-2-yl)-2,2′-di(methoxyethoxymethyloxy)-1,1′-binaphthyl (R-2) was synthesized by Pd-catalyzed Heck reaction of (R)-6,6′-dibromo-2,2′-di(methoxyethoxymethyloxy)-1,1′-binaphthyl (R-1) intermediate with vinyltriethoxysilane. The hydrolysis and polycondensation of the precursor R-2 produced the corresponding xerogel. Both precursor and xerogel were analysed by NMR, FTIR, UV, CD spectra, fluorescent spectroscopy, polarimetry and elemental analysis. The precursor and xerogel can emit strong blue fluorescence and are expected to have a potential application in the separation of chiral molecules as fluorescent sensor. The precursor exhibits strong Cotton effect in its circular dichroism (CD) spectrum indicating a highly rigid structure.

The crystal structure of [CoL(H₂O)₂]_n indicates that the complex consists of one cobalt(Ⅱ) atom, one L^2- unit and two coordinated water molecules, and the coordination number of the cobalt(Ⅱ) atom is six. One-dimensional chain supramolecular structure is formed by intermolecular hydrogen bonds and π-π stacking of neighboring benzene rings. CCDC: 652649.
