Structure of Supramolecular Assemblies Formed by α,δ-Tetramethylcucurbit[6]uril and 4-Nitrophenol

A host-guest assembly, [(C(40)H(44)N(24)O(12))·(C(6)H(5)NO(3))(8)·13(H(2)O)] (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-bon...

Descripción
Sumario:A host-guest assembly, [(C(40)H(44)N(24)O(12))·(C(6)H(5)NO(3))(8)·13(H(2)O)] (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.
