Formation of dynamic aggregates in water by cucurbit[5]uril capped with gold nanoparticles.
Supramolecular capping of cucurbit[5]uril (CB[5]) by gold nanoparticles has been achieved via a facile reduction of an aqueous solution of HAuCl(4) by NaBH(4) in the presence of various amounts of CB[5]. The resultant assemblies were very stable in solution, and were found to form dynamic aggregates consisting of a controllable ratio of singly and doubly capped CB[5].
