We found that the interfacially confined self-assembly of pyrene and phenanthrene glutamides can form strong exciplexes and amorphous superhelices, which show intensity-enhanced and sign-inverted CPL activity with improved quantum yield compared to a pyrene excimer. This work unveils the predominant role of supramolecular nanostructures over molecular configurations on CPL performance.
我们发现，芘和菲谷氨酰胺在界面受限的自组装过程中可形成强激基复合物和无定形超螺旋，与芘准分子相比，它们表现出强度增强且符号反转的圆偏振发光（CPL）活性，量子产率也有所提高。这项工作揭示了超分子纳米结构相对于分子构型在CPL性能方面的主导作用。
