Interaction of cucurbit[8] uril with Cobalt complex guests

Interaction between cucurbit[8] uril and Co3+ complex gust were detected by Uv-vis and IR analysis in details.The experimental results revealed that cucurbit[8]uril could form supramolecular structure with the metal complex guests in a ratio of 1∶1.Stability constants of inclusion of Q[8] with the guests were 104-107 L·mol-1.
