A series of polynuclear AuI–CuI complexes based on triphosphane and polyaromatic alkynyl ligands have been synthesized. All compounds obtained display dual singlet–triplet emission that originates from metal-perturbed intraligand and “intracore” transitions with a weak contribution from the gold centers in the latter case. Photophysical data were verified by quantum chemical calculations.
