We describe self-sorting supramolecular polymerization that uses chiral calix[5]arene hosts and a dumbbell-shaped fullerene guest. In a solution containing the racemic host and the guest, the (S)-host and the (R)-host preferably formed their homomeric complexes to form helical supramolecular fullerene polymers in a self-sorting manner. The self-sorting behavior has been studied using diffusion-ordered ¹H NMR (DOSY) and circular dichroism (CD) studies. The present findings show that it is possible to accomplish controlled supramolecular polymerization.

杯[5]芳烃与C60主客体络合引导的超分子富勒烯聚合中的自分选行为

我们描述了使用手性杯[5]芳烃主体和哑铃形富勒烯客体的自分类超分子聚合。在含有外消旋主体和客体的溶液中，( S )-主体和( R )-主体优选形成它们的均聚复合物，以自分类方式形成螺旋状超分子富勒烯聚合物。自分选行为已使用扩散有序¹ H NMR (DOSY) 和圆二色性 (CD) 研究进行了研究。目前的研究结果表明，可以实现可控的超分子聚合。
