Inclusion complexes based α,ω-imidazolium based oligosiloxane (Im-PDMS) and cucurbit[7]uril (CB[7]) in aqueous solution

Inclusion complexes of α,ω-bisimidazolium oligosiloxane (Im-PDMS) and cucurbit[7]uril (CB[7]) in aqueous solution were studied. The binding interactions were monitored by 1H NMR. Their annular aggregate morphologies were confirmed by TEM. The aggregation behavior of free Im-PDMS and Im-PDMS in 10−4 CB[7] were investigated using surface tension measurement.
