Combining Lanthanides with PyBox Ligands: A Simple Route to Circularly Polarized Light Emitters**

Abstract

We report the facile synthesis of TbIII and EuIII adducts able to elicit circularly polarized luminescence. Both the sensitization of the lanthanide-ion-centered luminescence (i. e. the antenna effect) and the chiral environment around the metal ions are brought about by commercially available enantiopure 2,6-bis(oxazolinyl)pyridine ligands (PyBox). This strategy is promising for the development of a wide range of new and simple circularly polarized luminescence (CPL) active LnIII adducts, thanks to the fine tunability of the chemical structure of the PyBox ligands.
