资源简介：
A novel pseudorotaxane of cucurbit[6]uril (CB[6]) and N,N′-hexamethylenebis (pyrazinyl bromide) was synthesized and characterized by 1H NMR, thermogravimetric analysis, and single crystal X-ray diffraction analysis. The crystal structure of pseudorotaxane was described, which self-assembled via hydrogen bonds of (H2O)3 clusters and formed two types of linear structures. Furthermore, Br−(H2O)3 anion clusters can serve as bridges to associate these linear structures and form three-dimensional networked pseudopolyrotaxane.
