【 摘 要 】

A host-guest assembly, [(C₄₀H₄₄N₂₄O₁₂)·(C₆H₅NO₃)₈·13(H₂O)] (1), based on a partial substituted cucurbituril, α,δ-tetramethylcucurbit[6]uril (TMeQ[6]), and 4-nitrophenol was synthesized and structurally characterized by single-crystal X-ray diffraction. A combination of hydrogen-bonding between the latticed water molecule and the hydroxyl group of 4-nitrophenol, the hydroxyl group of 4-nitrophenol and the carbonyl groups lining the portals in additon, the C-H···π interactions between the 4-nitrophenol molecules could be the driving forces of formation such an exclusion host-guest assembly.
