Daisy chain assembly formed from a cucurbit[6]uril derivative.
The building block synthesis of a derivative of CB[6] that bears a reactive propargyloxy group and its functionalization by click chemistry to yield 1 which contains a covalently attached isobutylammonium group is presented. Compound 1 undergoes self-assembly to yield a cyclic [c2] daisy chain assembly (1(2)) in water. The behavior of 1(2) in response to various stimuli (e.g., guests and CB[n] receptors) is described.
