Helical assemblies based on chiral tartaric acid derived acylhydrazones intriguingly exhibit excitation-dependent (ExD) emission through modulation between excited-state intramolecular proton transfer (ESIPT) and excimer emissions. By virtue of chirality transfer during the self-assembly process, an unprecedented ExD inverted or ON/OFF circularly polarized luminescence (CPL) switch was developed. This type of advanced CPL material can potentially be applicable in higher-level anti-counterfeiting and encryption.

基于酒石酸衍生酰基腙的螺旋组件的激发依赖性圆偏振发光

基于手性酒石酸衍生酰基腙的螺旋组件通过激发态分子内质子转移 (ESIPT) 和准分子发射之间的调制，有趣地表现出激发依赖性 (ExD) 发射。凭借自组装过程中的手性转移，开发了一种前所未有的 ExD 倒置或 ON/OFF 圆偏振发光 (CPL) 开关。这种先进的 CPL 材料可能适用于更高级别的防伪和加密。
