title: Complementary Binding in Urea-Based Self-Folding Cavitands.
abstract: A new family of cavitands bearing urea groups has been prepared. The hosts display a fluxional behavior akin to that of amide analogues. The ureido functions serve a dual role, stabilizing the folded conformer of the receptor and providing stabilization to guests present in the cavity.
