Abstract

The [2]pseudorotaxane of cucurbit[6]uril (Q6) with 1,6-bis(imidazol-1-yl)hexane dihydrobromide was synthesized and its crystal structure was described. The structure of [2]pseudorotaxane was mainly stablized by host–guest C–H···O interactions. Self-assembly of the [2]pseudorotaxane produces infinite one-dimensional chains with intermolecular N–H···O, C–H···O, and π···π interactions; thus, a linear non-covalent pseudopolyrotaxane is formed.

  7. General procedure for preparation of the [2] pseudorotaxane: A solution of 1, 6-bis(imidazol-1-yl)hexane dihydrobromide (0.1 mmol) in H2O (20 ml) was added CB[6] (0.1 mmol) in small portions and the mixture was stirred for 24 h at 80 °C. The solution was concentrated to 5 ml by evaporation. Addition of THF (30 ml) to the solution produced a white precipitate, which was filtered and dried in vacuum condition, affording the rotaxane complex.

  10. The crystals suitable for single-crystal X-ray diffraction were grown from its water solution evaporating at room temperature for over a week. Crystallographic data were collected using a Bruker SMART 2000 CCD diffractometer with MoKα (λ=0.71073 Å). Intensities were integrated using the SAINT program and corrected for absorption and other effects using the SADABS program. Structures were solved and refined using the SHELXS-97 and SHELXL-97 programs. All hydrogens were located in a difference Fourier map and their geometry idealized, and refined by using a riding model with O–H=0.85 Å (s.u.=0.02) and Uiso(H)=1.2 Ueq(O). The positions of hydrogen atoms, bonded to carbon atoms, were idealized with their thermal parameters of 1.2 times those of attached atoms.
