An innovative strategy for circularly polarized luminescence (CPL) of carbon dots (CDs) has been developed: The achiral CDs displayed contrary supramolecular chirality and opposite CPL in two different bi-solvent systems, which are due to the formation of self-assembled helical nanostructures with two diverse assembly modes (P and M) in aggregate state via intermolecular π-π interactions and differential hydrogen bonding (H-bonding) without the need of any additional element of chirality.
一种用于碳点（CDs）圆偏振发光（CPL）的创新策略已被开发出来：非手性的碳点在两种不同的双溶剂体系中表现出相反的超分子手性和相反的圆偏振发光，这是由于通过分子间π-π相互作用和不同的氢键作用，在聚集态形成了具有两种不同组装模式（P和M）的自组装螺旋纳米结构，而无需任何额外的手性元素。
