单手螺旋聚合物，间同立构聚（甲基丙烯酸甲酯）（st-PMMA），通过诱导配合机制识别高级富勒烯的大小和手性，并可以选择性地萃取高级富勒烯的对映体，如C-76，C-80，C-84，C-86，C-88，C-90，C-92，C-94和C-96。这一发现将产生一个实用的和有价值的方法来选择性地提取难以捉摸的高级富勒烯及其对映体，并开辟了道路，开发新的碳笼材料的光学活性。
A one-handed helical polymer, syndiotactic poly(methyl methacrylate) (st-PMMA), recognizes the size and chirality of higher fullerenes through an induced-fit mechanism and can selectively extract enantiomers of the higher fullerenes, such as C-76, C-80, C-84, C-86, C-88, C-90, C-92, C-94, and C-96. This discovery will generate a practical and valuable method for selectively extracting the elusive higher fullerenes and their enantiomers and opens the way to developing novel carbon cage materials with optical activities.
