Chiral coinage metal clusters show promise for use in emerging circularly polarized light-emitting materials and diodes but research on efficient circularly polarized organic light-emitting diodes (CP-OLEDs) with enantiopure metal clusters remains elusive. Herein, the authors design a multidentate chiral N-heterocyclic carbene (NHC) ligand which is used in the synthesis of enantiopure Au(I)-Cu(I) clusters with exceptional stability and demonstrate application of these clusters in the fabrication of CP-OLEDs
