基于新型帆船型络合物的超分子组装

Supramolecular Assembly Based on the Novel Sail-Boat-Shaped Self-Complexes

由于二芳基冠醚独特的大环型空腔结构及其对于客体分子的良好络合能力,利用分子内氢键成功设计了一类新型的、可通过酸碱控制其构型的帆船型自身络合物,对其进行了超分子组装,进而合成了一种新型索烃.通过利用分子间的电荷转移相互作用,以主体∶客体=1∶1的模板法,合成了一类新颖的索烃,利用了1HNMR、13CNMR、HRMS和1H-1HNOESY表征了其结构,希望通过改变酸碱环境控制其驱动.

Owing to the unique macrocyclic-cavity structure of crown ether and the capability of complexing with guest molecules, our group successfully designed and synthesized a novel Sailboat-Shaped self-complex by using intramolecular hydrogen bonds, which are able to switch its configuration during the different pH value. Furthermore, a novel catenane which based on the sailboat-shaped self-complex was obtained by using intermolecular charge transfer interaction and through the template-directed method, and its structure was identified by 1 H NMR, 13C NMR, HRMS and 1 H-1 H NOESY. It is hoped that it can be successfully controlled by the pH value conversion.
