Luminescent heteropolynuclear complexes of 3,5-dimethylpyrazolate [Pt2Au2M2(Me2pz)8] (M = Ag, Cu) showing the synergistic effect of three transition elements in the excited state.
Swap the coins! The Pt(2)Au(2), Pt(2)Au(2)Cu(2), and Pt(2)Au(2)Ag(2) complexes of 3,5-dimethylpyrazolate exhibit yellow-green, orange, and sky-blue luminescence, respectively (see figure). The emission energies of Pt(2)Au(2)M(2) complexes can be controlled by the change of the third coinage metal ions M. The Pt(2)Au(2)M(2) complexes take the cis configuration with respect to the Au(2)M(2) plane.
