摘要
基于2,7-蒽二胺和4,6-二羟基间苯二甲酸衍生物设计合成了交替的荧光二芳酰胺寡聚体A1和四芳酰胺寡聚体A2,通过引入缩乙醇醚链改善芳酰胺寡聚体在大极性溶剂中的溶解度.寡聚体的结构经~1H NMR和HRMS表征确认.据荧光滴定实验推测A2分子在极性溶剂二甲基亚砜中与均苯三甲酸客体分子发生主客体识别作用,其表观结合常数为1.95×10~3 L·mol^(-1).
A kind of fluorescence aromatic amide oligomer which based on 2,7-anthradiamine and 4,6-dihydroxyisophthalic acid derivatives is designed and synthesized. Tetraoxatridecanyl groups were introduced into the oligomers to improve their solubility in polar solvent. These structures were characterized by 1H NMR and HRMS. Fluorescence titration experiments indicated that A2 recognized 1,3,5-benzene-tricarboxylate ion by host-guest interaction. The apparent binding constant of the complex was measured to be about1.95×10^-3L·mol^-1, which opened a door on explore the supramolecular host-guest system by the track of fluorescence.
