摘要
设计合成了客体分子1-丁基-4,4'-联吡啶溴化物(BV+),利用核磁共振、紫外-可见吸收光谱、热重分析及X射线单晶衍射研究其与对称四甲基六元瓜环(TMeQ[6])的超分子自组装及形成的主客体包结配合物的结构特征.结果表明,在溶液中及固体状态下,TMeQ[6]均包结BV+的烷基链部分形成1∶1包结配合物.
One guest 1-butyl-4,4′-bipyridinium bromide(BV+) was designed and synthesized,while supramolecular assemblie of tetramethylcucurbit[6]uril(TMeQ[6]) with the guest BV+ was investigated by 1H NMR and UV-Vis absorption spectra,thermogravimetry analysis and X-ray crystallography in details.The experimental results showed that TMeQ[6] can preferred encapsulate the butyl moiety of the 1-butyl-4,4′-bipyridinium guest in its hydrophobic cavity to form inclusion complexes with a ratio of 1∶ 1 in the aqueous solution and solid state.This observation contributes to a deeper understanding in molecular recognition,design and construction of novel molecular machines.
