| Abstract: The experimental results reveal that solubility of cucurbit[n=5～8]urils is related with acidity of solution and metal ions. In hydrochloric acid， cucurbit[7]uril is the most soluble one， and cucurbit[8]uril is the least soluble one. There is no significant influence of alkaline metal ion on the solubility of cucurbiturils. The solubility of cu-curbit[7]uril increases greatly in a SrCl2 solution. However， increase of weight of cucurbit[n=5～8]urils suggest that cucurbit[n]urils can catch Ba2+ in a solution. |
