The synthesis of a chiral supramolecular organogel via the hierarchical helical self-assembly of optically active riboflavin and melamine derivatives is described herein. Owing to the photocatalysis of riboflavin and the supramolecular chirality induced in the helically stacked riboflavin/melamine complex, the gel is observed to act as a light-stimulated chiral sensor of optically active alcohols by detecting the change in color from yellow to green. The gel also served as an efficient chiral adsorbent, enabling optical resolution of a racemic compound with high chiral recognition ability.
本文描述了通过光学活性核黄素和三聚氰胺衍生物的分级螺旋自组装合成手性超分子有机凝胶。由于核黄素的光催化作用以及在螺旋堆积的核黄素/三聚氰胺复合物中诱导的超分子手性，观察到该凝胶通过检测颜色从黄色变为绿色，作为光学活性醇的光刺激手性传感器。该凝胶还作为一种高效的手性吸附剂，能够以高的手性识别能力对外消旋化合物进行光学拆分。
