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
