Abstract

The synthesis, molecular structures and luminescence properties of two ‘Cu₁₂S₆’ cluster molecules with stabilizing bidentate phosphine ligands are described. Both display in the solid state at ambient temperature high photoluminescence quantum yields (≥48%) and good stability towards oxygen.
