In hydrochloric acid, cucurbituril is the most soluble one, and cucurbituril is the least soluble one. There is no significant influence of alkaline metal ion on the solubility of cucurbiturils. The solubility of cucurbituril increases greatly in a SrCl2 solution. However, increase of weight of cucurbiturils suggest that cucurbiturils can catch Ba2+in a solution.展开更多

In this self-assembled entity both the cavity interaction of DCYQ6 included a nitrate anion and the portal interaction of the dipole carbonyls of DCYQ6 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.展开更多
