For chiral gels and related applications, one of the critical issues is how to modulate the stereoselective interaction between the gel and the chiral guest precisely, as well as how to translate this information into the macroscopic properties of materials. Herein, we report that this process can also be modulated by nonchiral solvents, which can induce a chiral‐interaction reversion for organogel
对于手性凝胶及其相关应用,关键问题之一是如何精确调节凝胶与手性客体之间的立体选择性相互作用,以及如何将此信息转化为材料的宏观特性。在本文中,我们报道该过程也可以通过非手性溶剂来调节,这可以诱导有机凝胶形成的手性相互作用的逆转。可以通过明显的胶凝速度差异和所得自组装的形态观察到这一过程。这种手性效应已成功应用于奎宁对映异构体的选择性分离,并赋予凝胶材料“聪明”的优点。
