3Temperature-driven braking of γ-cyclodextrin-curcubit[6]urilcowheeled [4]rotaxanes显示文摘Several cyclodextrin-cucurbit[6]uril-cowheeled [4]rotaxanes were synthesized through the cucurbit[6]uril-templated azide-alkyne 1,3-dipolar cycloaddition. The intramolecular interaction between the aromatic axle and the capping groups of cyclodextrin moieties was investigated by UV-vis, fluorescence,circular dichroism and NMR spectroscopic studies. The rotational kinetic of the wheel around the axle can be manipulated by adjusting the temperature. The capping group apparently slowed down the rotation of the wheel, playing a role of the brake, and lowering the temperature can stop the rotation of the wheel on the NMR timescale.Ran Liu Yuxue Zhang Wanhua Wu Wenting Liang Qinfei Huang Xingke Yu Wei Xu Dayang Zhou Narayanan Selvapalam Cheng Yang 2019Chinese Chemical Letters2019,30,3:0
