The first circularly polarized luminescence of achiral Eu-containing polyoxometalates (POMs) was realized by electrostatic assembly with a diblock copolymer containing bulky chiral pendants, and was unexpectedly enhanced by NaCl. The induced chirality is attributed to static coupling causing chiral torsion of POMs and dynamic coupling between organic chiral chromophores and an Eu emission center.
通过与含有庞大手性侧基的二嵌段共聚物进行静电组装，实现了非手性含铕多金属氧酸盐（POMs）的首次圆偏振发光，并且NaCl意外地增强了这种发光。诱导手性归因于导致POMs手性扭转的静态耦合以及有机手性发色团与铕发射中心之间的动态耦合。
