利用核磁共振技术、紫外-可见吸收光谱、荧光发射光谱、等温量热滴定及基质辅助激光解吸电离飞行时间质谱(MALDI-TOF MS)等方法研究了N,N’-二苄基-4,4’-联吡啶氯化物(G1,客体分子)与反式七元瓜环(i Q[7],主体分子)的相互作用及形成的主客体包结配合物的结构特征.结果表明,客体分子两端的苄基部分分别进入i Q[7]的空腔,而4,4’-联吡啶则一部分被i Q[7]的空腔所包结,另一部分处于i Q[7]的端口,形成包结比为2∶1的哑铃型主客体超分子组装体.
The effects of N, N’-dibenzyl-4,4 (4,4’-diphenyl-4,4’-diphenyl-4,4’-diphenyl-4,4’-diphenyl- ’-bipyridyl chloride (guest molecule) and trans-seven melon ring (i Q [7], the host molecule) and the structural characteristics of host-guest inclusion complex formed. The results show that guest molecules The benzyl moieties at both ends enter the cavity of i Q [7], respectively, whereas the 4, 4’- bipyridine is partially encapsulated by the cavity of i Q [7] and the other is at the port of i Q [7] Form dumbbell host-guest supramolecular assembly with an entrapment ratio of 2: 1.
