选取3个两端被不同长度烷基取代的紫精衍生物作为客体分子,利用紫外-可见吸收光谱、核磁共振技术、等温滴定量热、基质辅助激光解吸电离飞行时间质谱以及X射线单晶衍射技术等表征手段研究其与对称四甲基六元瓜环(TMeQ[6])的超分子自组装,结果表明这三种紫精衍生物与TMeQ[6]之间具有相同的作用模式,均为客体分子两端的烷基链部分进入到TMeQ[6]的空腔内,主客体以2∶1的作用比形成类似哑铃状的超分子自组装体.

Three symmetric viologen derivatives bearing aliphatic substituents of variable length were employed as guests, and the supramolecular self-assembly between teteamethyl cucurbit[6]uril (TMeQ[6]) and these viologen derivatives guests has been studied by 1H NMR spectroscopy, electronic absorption spectroscopy, isothermal titration calorimetry, mass spectrometry and X-ray diffraction methods in details. The experimental results revealed that there are similar interaction models between TMeQ[6] and three viologens guest, the alkyl chains of the guests are located inside the cavity of the TMeQ[6] host, whereas the 4,4'-dipyridyl moieties of the guests remain outside of the portal, forming a 2:1 host-guest inclusion complex.

Key words: TMeQ[6], viologen derivatives, dumbbell shaped, supramolecular, self-assembly
