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.
