Abstract

Three-component framework of cucurbit[6]uril, 3-(1-methylimidazolium-3-yl)propane-1-sulfonate and boric acid has been constructed. The crystal structure reveals 1:2 host-guest motif of cucurbit[6]uril and 3-(1-methyl-imidazolium-3-yl)propane-1-sulfonate, demonstrating both cation binding of imidazolium moiety and anion binding of sulfonate moiety for the first time. Incorporation of dimeric boric acid facilitates the formation of metal-free three-dimensional framework.
