Cupriphication of gold to sensitize d¹⁰-d¹⁰ metal-metal bonds and near-unity phosphorescence quantum yields.

ABSTRACT: Outer-shell s⁰/p⁰ orbital mixing with d¹⁰ orbitals and symmetry reduction upon cupriphication of cyclic trinuclear trigonal-planar gold(I) complexes are found to sensitize ground-state Cu(I)-Au(I) covalent bonds and near-unity phosphorescence quantum yields.
