title: Pseudopolyrotaxanes based polyhedral oligomeric silsesquioxanes and cucurbit[7]uril.
abstract: Pseudopolyrotaxanes (POSS/CB[7]) were synthesized using octaimidazolium-based polyhedral oligomeric silsesquioxanes (POSS) and cucurbit[7]uril (CB[7]) in aqueous solution. The binding interactions were monitored by (1)H NMR. Their regular octahedral morphologies were confirmed by TEM. The POSS/CB[7] was also characterized by FT-IR, thermogravimetric analysis (TGA), and elemental analysis. The TGA results show that the thermal stabilities of POSS/CB[7] can be improved by the threading of CB[7].
