Abstract

A new inverted cucurbituril, namely inverted hexamethylcucurbit[3,3]uril (iMe₆ Q[3,3]), has been isolated and characterized. It incorporates a single inverted un-substituted glycoluril unit oriented towards the interior of the cavity, shows good solubility in water and organic solvents (DMSO), and exhibits different selectivity for guests to those of iQ[6] and other known Q[6]s.

Keywords: cadmium; cucurbit[n]urils; host-guest interactions; structure-directing agent; supramolecular.
