Hexachloroplatinate(IV) anion-induced cucurbit[5]uril and cucurbit[8]uril supramolecular assemblies with linear channels

Two Q[n]-based porous compounds, Q[5]·[PtCl6]2 −·2H3O·12H2O and 2Q[8]·[PtCl6]2 −·2H3O·74H2O in cooperating the hexachloroplatinate(IV) anion ([PtCl6]2 −) as an inorganic structure inducer are demonstrated. The Q[5]·[PtCl6]2 −·2H3O·12H2O and 2Q[8]·[PtCl6]2−·2H3O·74H2O have permanent porosity may potentially be useful for gas storage, Moreover, the Q[5]-based porous compound displays selective absorption of tetrachloromethane, whereas the Q[8]-based porous compound displays selective absorption of methanol.
