We have found a simple and novel synthetic method for obtaining a chiral polymer from an achiral monomer by using a chiral catalytic system. The chirality of the polymer was caused only by a one-handed helical backbone, and the polymer had no other chiral structures in the side groups. In addition, the helical conformation was stable in solution by itself. This is the first example of helix-sense-selective
inducer was removed. The enantiomeric excess of one handed helix (eeh) is up to 98 %. Interestingly, the switchable helix-induction is visible with the naked eye. Moreover, the one-handed helices exhibit enhanced stability with helicitydiscrimination and enantiomerseparation abilities.
将一类外消旋聚合物诱导成单手螺旋,在去除手性诱导剂后将其记忆。单手螺旋的对映体过量 ( ee h ) 高达 98%。有趣的是,肉眼可以看到可切换的螺旋感应。此外,单手螺旋表现出增强的稳定性,具有螺旋度辨别和对映体分离能力。
