均苯四甲酸二酰亚胺拓展柱[6]芳烃与羧酸盐客体分子的络合性能研究

Study on the Complexation Properties of Promellitic DiimideExtended Pillar[6]aren and Carboxylate Guests

描述了均苯四甲酸二酰亚胺拓展柱[6]芳烃主体与羧酸盐客体分子在溶液中的络合性质,表明缺电子的主体分子与富电子的羧酸盐客体分子,通过分子间的弱相互作用力能够形成1∶2的超分子络合物.此外,主客体络合物的形成与解离具有酸碱的环境响应性,并且该过程也可通过肉眼进行观察.

The complexation between the pyromellitic diimide-extended pillar[6]aren host and carboxylate guests in solution was investigated in detail.It was found that the host could form 1∶2 complexes with carboxylate salts in solution.Interestingly,the complexation and decomplexation of the complexes between the host and the guest could be achieved by changing the pH of the solution,and the process could also be observed by naked eye.
