Abstract
Chirality sensing of choline derivatives is achieved by a self-assembled, racemic triple anion helicate cage which exhibits induced circular dichroism (ICD) upon encapsulation of a chiral guest. The host-guest interactions were illustrated by NMR, crystal structure, CD and DFT calculations. The absolute configurations and ee values were determined by ICD.
摘要
手性传感的胆碱衍生物是通过自组装的，外消旋的三重阴离子螺旋笼来实现的，当它包裹一个手性客体时，会显示出诱导圆二色性（ICD）。主客体相互作用通过 NMR、晶体结构、CD 和 DFT 计算来阐明。绝对构型和 ee 值通过 ICD 来确定。
