一种基于不可逆酰胺键与C―N单键的多吡咯分子笼:结构与阴离子络合
A polypyrrolic molecular cage consisting of irreversible amide and C―N single bonds:Structure and anion binding properties
摘要
Abstract
A chemically stable polypyrrolic cage constructed by irreversible amide and C—N bonds was synthesized through chemical reduction of its imine precursor.The structure of the molecular cage was characterized using NMR,MS and XRD.The anion binding properties were studied in deuterated chloroform or DMSO using NMR spectroscopy.The results indicated that this cage had a moderate affinity for anions such as Cl-,Br-,I-,HCO3-,AcO-and NO3-in CDCl3,and complexed with these anions in a 1∶1 mode through fast exchange,while the interaction with F-,SO42-and H2PO4-displayed slow anion-exchange kinetics.关键词
