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.

Abstract:

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.

Key words: TMeQ[6], 1-Butyl-4,4'-bipyridinium bromide, Supramolecular self-assembly
