摘要:

设计合成了2种不同碳链长度的客体分子1,1'-二甲基邻苯二甲酰亚胺基-4,4'-联吡啶溴化物 (G1)和1,1'-二丁基邻苯二甲酰亚胺基-4,4'-联吡啶溴化物(G2). 利用紫外-可见吸收光谱、 核磁共振波谱和等温滴定量热等方法研究了客体分子G1和G2与六元(Q[6])和七元瓜环(Q[7])的超分子自组装方式. 结果表明, 在加热回流情况下G1与Q[6]利用滑移法能与紫精基团包结形成[2]轮烷结构, 而Q[7]在常温下就能滑过封端基团邻苯二甲酰亚胺与紫精基团包结形成[2]准轮烷结构.

Abstract:

Two guests based on N,N'-phthalimide substituted 4,4'-dipyridyl with different alkyl chain lengths were synthesized(G1 and G2). The supramolecular self-assemblies of G1 and G2 with cucurbit[6]uril(Q[6]) and cucurbit[7]uril(Q[7]) were evaluated by UV-Vis spectra, hydrogen nuclear magnetic resonance(1H NMR) and isothermal titration calorimetry(ITC). The experiment results suggested that [2]rotaxane can be only formed between G1 and Q[6] in boiling aqueous solution by slipping. On the contrary, [2]pseudorotaxane can be easily formed between Q[7] and G1 or G2 in aqueous solution at room temperature.

Key words: Cucurbituril, Rotaxane, Viologen, Phthalimide
