The chemical structures of PVBCB, VBCB and VBDADC are confirmed by ^1H NMR,^13C NMR spectra and elemental analysis. In VBCB, CB[6] is localized aliphatic group of the side chain and the molar ratio of CB[6] to VBDAC is 1：1 .展开更多

The structure of the pseudorotaxane （CB[6]BPHP） is stabilized by host-guest hydro- gen bonds. Self-assembly of the pseudorotaxane produces infinite one-dimensional and two-dimensional networks with intermolecular hydrogen bonds. In the molecular packing of the CB[6].BPHP, C104（H20）2 water clusters serve as bridges to associate these pseudorotaxanes and form three-dimensional networked pseudopolyrotaxane.展开更多
